The bigger progressive springs were noticeable IMO when riding it a week apart after install. Maybe my brain was being tricked, but I remember telling my bud who owns it the time I rode it without the bigger springs, I thought that’s all it would need to be perfect for how we ride. And I was confirmed in my thought after he put them on and I rode it.

But I agree with @Doug S dont change them until you ride it stock. May be just what you are looking for in the ride.

Dynamix sleds come with a stiffer spring then a VR1

Still was a noticeable upgrade for how we ride.

I have a 2026 ordered. At what rider weight should someone consider different springs?
I bought it because of the reviews and the fact they are Fox shocks. Coming from many years on a Cat, I have grown to love Fox shocks.
I'm no expert, but the springs (for the most part) simply suspend the sled at the correct static height. The shocks really control compression and rebound as you ride.
I'm still a fairly aggressive rider... But I can say my experience with my 2022 ZR RR (Fox QS3R shocks) showed me that even aggressive riders can get beat up with harsh shock valving. But they will save you when hitting a crater at 75 mph (UP Trail 8 RR grade in the afternoon)

Ride it first. My wife is light, so we run her springs on soft. I am 210 suited up, and the only thing I could bottom the sled on was a huge G-out that any sled would have bottomed on. The shocks do a great job adjusting.

Those high G-outs are the weak point of the of the Pro-CC suspension.

In my opinion (and most motocross guys), if you don't bottom out every now and then, you're not using all of your suspension.

That's more than an opinion, that's basically restating a definition.

Full travel is measured from maximum unloaded extension to maximum compression.

I like mine to just kiss bottom in the worst case senerio hit to the suspension. I’ve rode a lot of sheds set up “plush “ that are downright dangerous on the unexpected big hit. The chassis defection could throw people right off or the whole sled can change course. So I 100 percent agree they should be able to use full travel but I think some confuse able to use and normal to use with no reserve. No reserve in travel in how guys get thrown and hurt on something they didn’t plan for or when pushing the sled past what they normally would. To stiff is another danger. Anyway I believe guys over 200 that ride rougher stuff will need a revalve. Everybody I know who pushes a sled that said it didn’t need anything were sub 200. With that being said I also agree ride it first one may find they don’t need a revamp just a tweak to the fts.

Yes to "soft" bottoming, but if it just blows through the travel and slam the bump stops, then up your spine, then it's no.

What you need to be a where of is going with heavier springs your now also changing the rebound speed of your shock. Heavier springs are now speeding up the rebound of the shock where the sled could be bucking you off. You may be revalving the shock to slow down the rebound

 

[just-pinch-it]

Yes, heavier springs will require the rebound to be slowed. The dynamic system sounds impressive, but for some, springs and valving will still be needed. There is limits of the on the fly adjustments that it can fix.

What does polaris say about the use of stiffer springs on the dyna-mixer for heavier riders?

 

[ExcursionPSD]

At this time, Polaris directs you to use Rear Torsion spring adustment or replacement to adjust the balance of the sled (Balance between weight transfer and ski pressure). Light or heavy riders should consider installing optional torsion spring pairs.

They do NOT have specific spring guidance for Dynamix suspensions. The owners manual, has some significant faults at this time.

So many dont understand how important this is… 👍

I’d like to try lighter torsions on my wife’s, but I don’t want to be the first one to try it lol

You can also split the torsion springs. Run one side with the stock spring and one with the light. Gives a middle setting between stock and light

We have over 1500 miles on our Dynamix. Overall, a very impressive sled. It works.
Positives: 1. Better riding. 2. Flatter cornering. Less rider input needed to go fast. The 3 modes change the starting stiffness of the shocks. We use the middle mode(Rally) the most. 4. Extreme mode is great on smooth/fast trails, but too stiff for moguls. 5. You will notice that sled is significantly different than a normally equipped model once you ride one. Ride them back to back and you'll agree.

Negatives: 1. Could use more compression/rebound dampening for more aggressive riders in Rally mode. But not much more is needed. 2. Expensive. 3. Shock rebuilding is more expensive. 4. The switch to change modes should be handlebar mounted, it's difficult to reach when riding.

Overall, we are happy with the sled and will keep it for another season. I'll most likely send the shocks to Bruce and Jessie at Southside in Mass this fall for a rebuild and upgrades. We do have Tanner's progressive front springs to try later in the season. Bruce and Jessie seem to think that this improves the ride and handling.

Yes it does!

 

[Doug S]

Yes it does!

Had my XCR with the progressive front springs and my wife's did not. Rode them back to back multiple times and it was a noticeable improvement. Have a set on order for my wife's 650 Dynamix that's coming.

Where is the switch located?

opposite of the key , i plan to move mine up on the bars .
