Great Kit ... #1 Suspension Upgrade recommend to our customers.
I installed this spring kit on my 2021 Polaris XP4 Turbo, the difference is night and day. Much more plush feeling and better handling. I had another brand of spring on my last RZR and while they were pretty good these seem to be better in terms of ride quality, and the silent crossover rings get rid of that annoying clanking sound when the isolator hits it. Well worth the investment. I hope to be able to get you guys to do the valving on my shocks soon.
Great kit. Install was easy. The kit works great kit that really allowed me to take whoops and chatter at higher speeds with a much more stable car. Much more comfortable.
They work great watch the Instal video it helps a ton!
One of the greatest purchases I have ever done u guys are fucking amazing!!!!!!
Amazing product. I can believe how much better it rides and how much easier it is to control.
Freaking amazing way more plush. Spot with the ride heights didn’t even have to adjust just followed there Recommendation. A Must have
Well we had tenders on ours . We’re not what we needed called shock therapy called me right back and ordered online they helped me every step of the way wow
This spring kit really smoothed out my factory ride and gave me better control and feel in the chop at the dunes. It also lifted the car a little overall great kit wife is much happier with the ride. The only thing I would change is the cross over ring design doesnt give you much real estate when installed on the car to use a spanner or screwdriver to adjust
