Great video. Thank you!

Hi. Is it a problem to add only one (1) stiffer torsion spring. My problem is going with both stiffer torsion springs will be way too stiff.

This is very helpful. When setting the sag, should I not have my gas caddy or anything else on the back? Just curious if it should be like me riding the sled on the trail or just with nothing on it in the garage. Also, what tool did you use to adjust it so quickly and easily? Thanks.

What spring do u recommend for 450 lbs ? Vk540 2017

Your video is the most informative that I have ever seen pertaining to how a snowmobile suspension shock system works. Thank you so much. I sprung for aftermarket shocks (Elka and Exit) and have been struggling to adjust the shocks to be at least better than OEM. Still not there but hopefully your videos will help me to find the sweetspot. Hopefully the spring selection and damping range was built properly for my use. Again, many thank you's. And yes I subscribed.

Helpful video, thank you!

Don't know if you answer questions here. But what's the cons of having too fast of rebound?

John, when you're trying new rear torsion springs for a sled, no you initially try setting the sag with the adjuster set to the 'middle' allowing for adjustment in both directions? I se online guys throwing springs at sleds but no mention of where the adjuster is. Like you mention in the video, the sag may be OK for a 'light situation' but if you're maxxed out on the adjustment in either direction in a lightly or loaded condition, you may not have any more adjustment.

Lots of xrs's with KYb's have rebound adjustment

I would have paid money for that information, Thanks John !

👍👍

👍👍

Those look like my stage 4 shocks sitting next to you. Yamaha vector xtx singleshot suspension.

love watching your videos very helpful keep them up look forward to seeing you on the trails

Great Video John 👍🏼 Soon I’ll be installing the set of 4 Elka Stage 5 shocks I ordered from you last fall for my ‘22 T-Cat.. I took delivery very late in the season so I’m looking forward to running the sled with Elkas this winter. 😁 Take Care

All of us sled addict's are getting antsy 😂😂😂

Great information. I've just recieved some ski springs, rear center shock spring and an adjustable limiter strap for my XRS. That's about all I had in the budget at the moment but I feel like a rear shock with some rebound adjustability is in my future. Look forward to trying out your products this winter!

Rip thru the chop at "50km/hr".. the look on your face says it all sir 😇

The math equation finally set the lightbulb off over my head. Great information. Thank you for your knowledge.

Do you have a setup for wanting a more playful ride?

Videos are great! Can you do a 22 polaris xcr? A lot of people are not happy with the suspension on them.

This is great info! Your videos are so incredibly informative. I guess the guys at @SnowTrax were spot on in their assessment of the Ski Doos front end handling, despite all the hate they received. 🤔

due to my lack of research i went with skidoo 1.66/80 as a 280 pound rider this isnt enough torsion. im a semi aggressive trail ridder on a 2020 back country 850. ill try these but ill probably be calling you

As a 6'7 300 lbs rider the torsion spring you guys have sent to me have given me a far better and planted ride that is a 100% improvement. Thank you so very much for the video and time you guys have given .

Thank you so very much for all the information. Spoon fed to make me understand easier.

Fantastic video. Thank you for sharing!

Can you tell me what size of spring I should consider for a 2016 Renegade 800 XRS. I am 225-230 and my wife would like to ride along on the 2-up seat we purchased and she is 125 so let’s say with gear 400 pounds. When I take the sled out myself I have the adjustments maxed but the sled still wants to ride close to the ground with the flap dragging, no wife on the sled as of yet. Thanks so much - Tim

Nice video. Wish you would of told us rider weights on all the springs.

Man, I’m really glad I found this. Bought an xrs and have really been trying to learn how everything was supposed to work so I can set it up for myself and make the right adjustments. Glad I learned a little something. Just looked at my a arms though and it looks like I have some work to do. Definitely not level!!

Would it be too much trouble to ask how to tune the preload of the center shock and limiter for a snowmobile? This is the information that I'm finding hardest to find.

Never showed how to set it. Not good video at all

So number 3 on the stock torsion springs on the rmotion x ? I’m about the same weight as you so good enough lol

I did check your web site for info on AC/Yamaha springs and see you have not posted anything yet. I will continue to look at it. Thanks for the videos.

I'm waiting on delivery of a Sidwinder XTX 146 and am researching suspension springs. Information is hard to find even on the I-net. Thus stumbling on your site has proven valuable. Based on my findings thus far, AC/Yamaha's STOCK spring rating is 0.394" SQ, - 90Deg. Angle - 165 LB. They offer a upgrade rated 0.405" SQ, - 85Deg. Angle - 191 LB. I have a friend with a AC racing sled 2017, Model 600SX . I was only able to measure the long arm at 0.437" SQ. I have not found any additional info on that spring. My reason for doing this research is - I will be building a rack on the back of the tunnel to carry my ice fishing gear. I'm 200 lb, by the time I'm dressed, probably 220 to 225 lb. The fishing gear - auger, rods, tackle, sonar, heater, propane, etc going in the rack will probably weigh 60 to 80 lbs. So, I pretty sure the stock spring would be replaced.

Just booked an appointment for two sxs, you guys seem knowledgable and customer service has been great already, can’t wait to get our buggys in for some needed treatment!

I love your videos. Very informative. Do you sell springs to the public and if so would you ship? I am in Nova Scotia and am riding a 2017 Skidoo MXZ Blizzard.

So if I do not have the dollies, can I just set this on the floor?

Curious: What's the best sled/setup you've ridden at the Haliburton Forrest? Money no object

Generally, you should get a static sag measurement, and then determine the amount of rider sag from the static sag measurement ... rider sag should not be determined from an uncompressed suspension, as you've demonstrated here. Also, as you point out, rider sag should be measured with the rider in full gear, as well as with anything else you plan to carry. Something this video lacks is how to determine proper sag (you could at least mention whether the sled manufacture has a recommending range, and where one can look to find this info). I don't know if you intend to make a video showing what adjustments should be made to bring the sag into the manufacturer's recommended range, but if not, you also left out how to adjust spring pre-load, and what effects will occur with adjustments to each shock in the skid.

Great job John and Jen! I've been watching a bunch of you vids. Sounds like more are coming. Hoping to come see you before next season for a consult and possibly dual rates on my stock WE's.

Great explanation! Thanks for putting this video together 👍.

I will be making an appointment in the New year. You are doing some amazing work for suspension needs. You are way ahead of the curve then other shock builders in this part of Ontario anyhow.

Looking for advice on how to setup suspension on a 850 renegade skidoo for drag racing Thanks

Have you had a chance to take a close look at the 21 MXZ XRS suspension? I would like to bring the ride height of the XRS down a little over an inch to the ride height of the MXZ X without upsetting the balance.

Something seems wrong with this theory, if the tender spring was in fact 4.0 and the main a 2.0, the tender spring would not compress before the main spring. Tender springs are supposed to be softer, not harder than the main spring.

We plan on having the new 2021 XRS models in the building this summer and we will confirm Shock and spring fitment at that time. We suspect all is the same, but Ski-Doos claim of more travel may mean we need to design longer Elka shocks, but our hope is that our spring kits from the 2017-2020 Gen 4 XRS and standard X and TNT etc models are the same. We will keep you posted!

I have a 2021 XRS 850 Renegade on order. Would be interested in a spring package for the RAS X and R-Motion X skid.

Let me know when you have developed something for next year’s XRS with the longer shocks.
