SMART SHOX SUSPENSION FLASH - ***NEW*** STAGE 2.0 !

We are super excited to announce the release of this addition to Accelerated Technologies' original Suspension flash for the Ski-Doo KYB SMART SHOX equipped snowmobiles from BRP. Created in partnership with PRECISION EFI who's help allowed us the ability to access and flash the Suspension ECU. We are jointly offering this new advanced flash.

QUICK REVIEW OF the original STAGE 1.0 released in 2024:

We implemented these following improvements over stock:

COMFORT MODE / SKI SHOCKS - Ski shocks were WAY TOO SOFT stock. We firmed this mode up so that it is usable at a moderate trail pace. We also increased the rebound damping to better 'hold on to' the ski at this new pace.

SPORT MODE / SKI SHOCKS - Stock, this mode was barely firmer than COMFORT mode, we bumped it up a moderate but noticeable amount over Comfort Mode with Stage 1.0. We also adjusted the spread of damping at different shaft speeds to better match the rear. (keeping the sled flatter as you flipped through the modes).

SPORT + / SKI SHOCKS - Stock, this mode was massively strong, too strong for the trail. It seemed the supplier was going for shock value here and overshot the mark for trail riding. We softened this mode at some (shock) velocities so it was far more usable by the average aggressive rider, but retained the BIG hit protection. Basically just a bit firmer than SPORT mode.

COMFORT MODE / REAR - Again, like the front we found this mode to be too soft to be usable. We firmed up the low speed damping fairly significantly to keep the sled up in the top of the travel as that is where the R Motion X skidframe gives best comfort. We also boosted the rebound slightly to hold on to a kicking sensation the sled had on bigger hits.

SPORT MODE / REAR - Stock this mode was ever so slightly firmer than Comfort mode. We bumped it up primarily at low speed to give a 'sportier' feel, but noticeably firmer than Comfort Mode.

SPORT + MODE / REAR - In a similar trend to the Skis, we found this mode to be too firm to be very usable in the bumps with a HUGE problem in the rebound damping that we corrected.

STAGE 1.0 OVERVIEW:

The above fixes were (and will remain) available as Stage 1.0 for $599 Cdn. We recommend the correct Torsion springs (see charts on our Website) and an optional compression k**b installed on the rear shock to tune the compression damping manually (in addition to the mode selected) to give even more rear shock control. Up front we recommend our Dual Rate Ski shock spring kit to better match the R Motion X skid out back by making the front suspension Progressive. IT IS NOT mandatory for the tune at all, we just find the sled handles flatter and stays better balanced.

SUSPENSION FLASH -STAGE 2.0 ***NEW***

We were excited to update our first version after 2 years of LEARNING and testing with our ELKA shock packages on non-SMART SHOX equipped machines. The ELKA shocks give us unbelievable control with low speed, high speed and rebound damping control. We have tested a new theory of valving on the Elka shocks with incredible results, and we applied this knowledge to our SMART SHOX SUSPENSION FLASH Stage 2.0. During testing, we data logged with our onboard telemetry data logger on the Elka machines AND have been data logging on the Smart Shox Sleds as well. We were so excited to apply this new 'loop' of knowledge to the SMART SHOX Stage 2.0 flash.. With the engineers at PRECISION EFI, we would develop a "target" group of shock settings on the Shock Dyno, then ride it on trail with our test riders, then debrief our ride recording our detailed impressions. We then look at the data from the ride to close the 'loop' begun at the dyno. We then ensured the sled stayed flat and balanced as we progressed up through the 3 modes with nice steps on each setting as the dyno alone does not ensure this. No more Goldilocks settings of WAY TOO SOFT and WAY TOO FIRM. We improved the compression and rebound balance with the help of the data to give us an incredibly comfortable, flat, predictable, fun snowmobile.

COMFORT MODE / SKI SHOCKS Stage 2.0***NEW*** - We made this mode a little firmer than Stage 1.0 holding the sled up in the top of the travel where comfort lives. We learned that at times, firmer means more comfortable due to the ride height maintaining more travel below. We also spent a ton of time making the rebound 'progressive' to better match the spring push (especially with the dual rate springs). This improves comfort AND grip from the skis, giving us an elevated level of safety and carbide traction that we didn't know was even possible.

SPORT MODE / SKI SHOCKS Stage 2.0 ***NEW*** - Same theories applied above, just 10% stronger with upgraded progression through the stroke which helps the ski stay dug into the snow at all positions. For example we have the rebound stronger when the spring is pushing harder (from deep in the travel) and slowly back off the rebound as the spring relaxes and the shock slows down. This keeps incredibly even 'push' of the ski into the trail.

SPORT + MODE / SKI SHOCKS Stage 2.0 ***NEW*** - Same as above, just approx 10% stronger again. Reminder SPORT and SPORT + have an auxiliary map that adds damping to the outside ski as the bar is progressively turned. We have logged at least 5 increases in damping between bars - straight and 20 degrees of bar angle. This works like a 'progressive' sway bar to help keep the sled flatter when ridden aggressively in the corners

COMFORT MODE / REAR SHOCK Stage 2.0 ***NEW*** - We spent a tremendous amount of time on the rear shock in Stage 2.0. We found (even with Stage 1.0) that the rear shock was very sensitive to damping progression when coupled with the rising rate linkage of the R Motion X skid. The shock had the tendency to be soft in the top of the travel, then try to stop right around half travel as the damping firmed up, which would manifest itself with the rider crushing into, then getting ejected out of, the seat. The good news is that it would hardly ever bottom, but it definitely left some comfort to be desired. For Stage 1.0 we 'flattened' the damping curve as best we could, but this tendency still existed which we controlled with elaborate rebound. For Stage 2.0, WE WORKED WITH OTHER AUXILIARY MAPS THAT WERE ADDING DAMPING DURING ACCELERATION AND DECELERATION. In layman's terms the compression damping was getting firmer on throttle opening (acceleration) performing an anti-squat function. With our heightened expectations of comfort, we worked on these auxiliary maps that affect the base damping map to allow us to use much more travel... Which means increased comfort AND bump capability.

SPORT MODE / REAR SHOCK Stage 2.0 ***NEW*** - We applied the same fixes as in Comfort mode and also adjusted the SHOCK LENGTH BASED DAMPING curve which was adjusting the base damping dependent on the position of the shock. We also embraced and incorporated the braking map and it's effect on rebound damping. This map controls the pitch forward during corner entry. We polished this one too.

SPORT + MODE / REAR SHOCK Stage 2.0 ***NEW*** - Same improvements as with the above maps, just stronger with enhanced auxiliary map control. Carefully balanced to the SPORT + Ski maps to ensure the sled stays incredibly flat through the corners. Our Dual Rate Ski and Dual Rate Pro 40 Centre shock spring kit helps optimize these improvements even more.

SUMMARY STAGE 2.0 - Basically, we incorporated base damping improvements that we have discovered in the last 2 years during thousands of shock dyno runs coupled with what we have learned data logging on the Smart Shox machines. Even more importantly, we are utilizing the MORE ADVANCED MAP CAPABILITIES IN THE SMART SHOX MODULE. We leveraged and improved what makes the SMART SHOX.... SMART, by working with the more advanced maps within the Suspension Module. We greatly increased how much active travel is in the rear shock to give big boost in comfort out back in all modes, while ensuring the sled stays 'flat' front to back regardless of which damping mode is selected. So, greater comfort AND greater performance in all modes.

STAGE 2.0 will be at a special release sale price of $799 Cdn or upgrades for $200 for existing owners of the Suspension Flash Stage 1.0. Again, we recommend the correct Torsion springs (see charts on our Website) and a compression k**b installed on the rear shock to tune the compression damping manually (in addition to the mode selected) to give even more personalized rear shock control. Up front we recommend our Dual Rate Ski shock spring kit to better match the R Motion X skid out back by making the front suspension progressive. IT IS NOT mandatory for the tune at all, we just find the sled handles flatter and stays better balanced.

Note: RAS RX owners. The Suspension flash is indeed the same for this latest front end, we just have an upgraded dual rate spring kit from Accelerated Technologies for the RAS RX that we developed to offset the leverage change from the new front spindles and flatter shock angle.

Note 2: We continue to remind everyone that the Smart Shox are incredibly hard on the OEM shock oil and we recommend getting the shocks serviced at the 3,000 - 5,000 km interval MAX by a reputable shock service centre with a vacuum bleeding machine.

Note 3: As before, the Flash Stage 2 will be available at Accelerated Technologies, Precision EFI or at participating Precision EFI dealers worldwide. Just like with a Precision EFI engine tune, the Suspension tunes can be flashed into the diagnostic port located by your right knee when seated on the sled. Optionally, the Suspension Module can be sent in and "bench flashed" at any of the partners named above. It can be located on the main frame rail under the hood, near the top of the left hand shock mount and it says KYB on it. Price is the same for either method of installation. 👍🤓

2026 EXPEDITION SHOCK COMPARO

On behalf of Elka Suspension, Accelerated Technologies is designing a much-needed shock package for the 2026 Skidoo Expedition series of utility machines.

Here is a quick SHOCK COMPARISON of the centre shock options between the LE, SE, and Sport versions of this 154 inch machine and the higher performance Extreme version of the machine.

None of the centre shocks have any damping control (hope you like it) and only the Extreme has an aluminum body shock with enough preload adjustability to get to zero preload if you are running a groomed trail and want to get the tippies out of the machine.

ONLY THE EXTREME VERSION OF THIS CENTRE SHOCK IS EVEN SERVICEABLE, KEEPING IT OUT OF LANDFILL WHEN IT’S TIME HAS COME for service. 

At the end of the video, I show the Elka Stage 5 and It’s features and benefits to this awesome snowmobile. I use the Stage 5 (hi speed comp, low speed comp and rebound) for development due to reservoir clearance fitment confirmation as well as tuning the base valving, but you can also get the:

Stage 4 which is a piggyback shock with low speed compression and rebound…

or for even less investment:

Stage 2, which has no piggyback reservoir yet still has a rebound adjust k**b plus dual rate springs custom selected by Accelerated Technologies for your application, as well as infinite body threads for tuning the centre shock support.

All Stages feature dual rate springs that give you protection for the big hits as well as a softer start rate to keep the machine going straight, smooth and predictable down a packed trail.

Contact us to get yours on order for this fall for a huge improvement to your Expedition. Obviously, we have also completed the rear shock for all models as well as the ski shocks featuring progressively supportive, dual rate springs and full damping control for unmatched comfort and protection!

REMINDER: DUPONT VESPEL SLIDES!

We currently have great inventory on the super hard, super durable slides with DuPont’s trademark Vespel inserts moulded in.

These sliders are much, much tougher than the base material and as such last quite a bit longer, especially in low snow conditions. They also reduce rolling resistance which should manifest itself in higher top speed potential and improved fuel economy.  But really, the dramatically higher temperature it takes to melt these slides makes the durability their biggest selling feature. 

Yes, they are pricey, but if they save you on that one dry road side, heading into or out of a town where snow is scarce, it’s worth it. Also with a 3 to 4 times longer life expectancy than stock you are saving on downtime and installation costs if you’re not doing them yourself.

Anyway, we’ve got them for all brands. Just make sure for Yamaha you specify whether it is a Japanese Yamaha (eg Apex/Vector/Nytro etc) or a Cat built Yamaha (Viper/Sidewinder etc) as obviously they are quite different. These two platforms run different rails. Price and availability is on our website.

If you would like a set installed during your suspension set up appointment this fall, please let us know. It wouldn’t be a terrible idea to let us know ahead of time so we can put your name on a set because these often sell out fast, especially Polaris, they are very hard to get for some reason. If you don’t have your set up appointment yet, and you want one, give us a call soon! Spaces are filling up fast. 

Or of course, we can ship slides to you if you can’t make it in. 👍👍👍

A VERY POPULAR KIT!

08/21/2026

A SUPER POPULAR KIT:

SERVICE SMART SHOX- Remember these things RUIN the oil in 3-4,000 km due to the strong valving and busy solenoid.

CORRECT TORSION SPRINGS - Like the foundation in a house, don’t invest above if the basement can’t take it lol. The right torsion springs will hold the vehicle up off the centre shock and in the soft plush upper part of the travel and keep the weight on the skis on throttle exit.

DUAL RATE CENTRE SPRING KIT - A proper progressive spring arrangement on the centre shock removes the tender spring breakage failure from the OEM design. Also, our shorter custom length permits zero preload at shorter limiter strap settings to keep the weight on the skis for improved handling.

DUAL RATE SKI SPRINGS -  This spring kit makes the front arms progressive to match the rising rate function of the rear skid frame. The sled not only sits slightly lower out front, but stays much flatter through the bumps. We can give a softer more comfortable top rate while running down the trail and a strong end rate to prevent bottoming on the bigger hits. 

ADJUSTABLE LIMITER STRAP - This device allows you to quickly (30 seconds) balance the centre support on the snowmobile to give you the handlebar effort and ski pressure you want. It is to be adjusted in tandem with the centre spring preload to effectively give this control. 

GREASEABLE SPRING GUIDES - This is v 2.0 which features tough threaded-in grease fittings. This allows you to grease the underside of your torsion spring to delay or prevent the onset of rust where the spring slides though the guide. This dramatically improves the small bump comfort by reducing the friction needed to move the skid. 

SUSPENSION MODULE REFLASH - this popular reflash improves significantly the three settings of Comfort, Sport, and Sport Plus. Version 2.0 will be released September 1 and features a host of added improvements over the already impressive Version 1.0. More will be released on this in the next week and a half.

BERGSTROM TRIPLE POINT CARBIDES-
Our favourite for longevity over dirty terrain or weak snow conditions these things just hold up and keep on wearing.

COMING IN THIS FALL? Perhaps for your shock service and suspension set up? WHILE YOU ARE HERE, we can install a PEFI engine tune!

NO WAITING.... WE HAVE Skidoo ECUs IN STOCK FOR SAME DAY EXCHANGE. The one drawback we hear about Precision EFI is that you have to send your ECU away to them to have it 'unlocked' and flashed, then wait the one day to get it shipped back (Jeesh). Well.... we have done that for you. WE STOCK NEW UNLOCKED BRP ECU's FROM PRECISION at our shop so you can get your Popular Engine upgrade Stages completed SAME DAY.

Just let Erica know so we have enough Technicians on your machine when it comes in for the supporting products for the Engine Flash. Most popular are Primary Clutch kits (needed for the increase in power), HD secondary rollers, large diameter PEFI Down Pipes with O2 b**g, Airbox Clamp kits (that glue lets go over time especially with increased boost), High Pressure charge tubes (Red or Black) and higher flow intercoolers (more popular if upgrading your std 130hp turbo vs the Turbo R).

Don't have your Suspension Set up and/or service booked yet.... Better call now, spots are filling up fast. 705-657-9490. Already have your appointment booked but thinking of a nice power boost for the season? Call us and get it added!

I am hooked. I put the Stage 1R on my Expedition and OMG, Fun! That 20" wide 154 with 230 HP puts a grin on my face that lasts for weeks... So worth it... You know cause we really need 200+ HP 😆

TECH TIP.

This is the lower cross shaft assembly in the centre shock in an Arctic cat/Yamaha pro Cross skid frame.

The design of the skid frame uses short travel shocks with big leverage ratios, which puts a lot of load on components. It’s still early, so pull this shaft out and examine it. We replace tons of these each year when installing ELKA shocks or servicing OEM dampers.

On most skid versions, this lower shaft is aluminum with a gray anodized finish. Usually a few years in from lack of maintenance or cleaning, it will wear through the anodizing and quickly compound big clearance as the soft aluminum shaft rapidly gives up.

Give your lower suspension shaft a look at and replace if it has worn through. If you are handy, you can carefully knock a grease fitting into most lower shock eyelets, or on our website we sell WURTH RED spray grease, which creeps in beautifully to lubricate this high load area.

A quick sq**rt of WURTH RED GREASE on either side of the shock every few rides will keep that joint moving smoothly which translates to better bump absorption, and improved suspension compliance, as well as holding off the damaging effects of wear.

THE CENTRE SHOCK. HOW IMPORTANT IS IT?

Here is a short video discussing the differences between the new AC5S shock on the new Arctic Cat Catalyst, and our favourite go to the Elka Suspension centre shock damper.

We have had several complaints from some of our Cat customers with this snowmobile, so we thought we would take a close look at some of the limitations of this damper.

This particular shock only seemed to have three compression settings on the Dyno, not five, and an excessively long spring, which prevents you from shortening the limiter strap without adding unwanted centre preload. As well, we found the rebound damping to be both too light to hold the front of the skid unloaded to maintain ski pressure in higher frequency bumps and it is unadjustable in terms of rebound tuning. Centre shock rebound control, we have found to be a massive tuning benefit for constant ski pressure through the bumps.

So, if you are looking to just buy one shock absorber for your snowmobile to dramatically improve handling, be it an Arctic Cat, Yamaha, Skidoo, or Polaris, consider replacing the centre shock with a unit that has the ability to shorten the limiter strap without adding preload, as well as both compression and rebound damping. It will be a game changer for you.
