This is a true dual-rate spring kit with adjustable crossover collars from Schmidty Racing Suspensions for the Polaris PRO XP Ultimate and PRO XP4 Ultimate with Fox Live Valve Shocks. Our spring kits feature top of the line Eibach brand springs which replace the low quality / saggy / poor riding OEM springs. Ask our competitors what springs these use as many will not be able to claim using Eibach springs. The sliders that we include in this kit are a thicker wall material than what comes factory from Polaris and will not breakdown like the OEM ones.


These are not Eibach kits (Stage 2 or 3), but feature our own tested and tuned spring rate combinations using an Eibach coil to provide you the best ride quality possible.

This kit will only fit Fox Live Valve Shocks that come standard on Polaris Pro XP Ultimate and Pro XP4 Ultimate editions. This kit will not work or fit Walker Evans shocks. If you have an XP Pro with Walker Evans please purchase through our other item listed.

With our dual rate spring kit you can expect to:
  1. Regain lost ride height.
  2. Receive a truly plush ride eliminating most of the trail chatter feedback you get from embedded rocks, ruts, tree roots, tire tracks, etc. with the lighter initial spring rate of both springs active.
  3. Superior bottoming resistance when the spring separator contacts the crossover collars and engages the heavier main spring solely for the remainder of the shock stroke.

The beauty of this kit is that it is truly adjustable! The threaded crossover collars can be infinitely adjusted "up" or "down" on the shock body thread, to set the point in the stroke where the spring separator contacts the cross-over collars and engages the heavier main spring solely for the remainder of the shock stroke. Either hardware style of our spring kits are totally user friendly and require no shock modification to install. Installation only requires basic tools and 3-4 hours time. Our dual rate spring kits come with a detailed and complete, step-by-step installation instruction sheet with settings, diagrams, and photos.

Full Replacement Spring Kits Include:

  • (1) Installation Instruction Sheet
  • (4) Delrin Spring Separator / Slider
  • (4) Threaded Locking Crossover Collar (2023 OPTION WILL NOT INCLUDE THESE)
  • (2) 2 Piece Crossover Collars for the Rear (2023 OPTION WILL NOT INCLUDE THESE)
  • (8) Quality Eibach Springs (4 tender & 4 main springs)
  • * Each kit does all four (4) front and rear shocks*

We use quality Eibach springs in our kits, because they are the best! While Eibach is not the cheapest spring, we want to provide you with the best possible kit when you go to upgrade your ride with replacement springs. Eibach springs, combined with the features of our Schmidty Racing Suspensions hardware, create a spring kit that is second-to-none in the industry! Customers who have chosen our proven kits have been thrilled with the ride and performance we offer. Many of our customers originally used spring kits from our competitors before coming to us, but after being disappointed with others' results they tried ours and wholeheartedly affirm the superior quality.

5 of 5 Absolute must have September 21, 2022
Reviewer: Brayden  
Every Pro XP owner should have this. My machine is a 2022 and within the first 1,000 miles my upper springs were already fully collapsed. I lost travel, I lost ride height, and I also lost a lot of comfort. Everywhere I went I had to be in the "Firm" setting just to avoid bottoming out. Side by side comparison of the springs showed just how cheap the factory ones were. My only regret is that I didn't do this the day I bought the machine.

Reviewer: Kevin Paxton from Roseburg, OR United States  
Installed springs without the revalving(will do at later date). The springs performed awesome on the Oregon dunes for my long travel suspension.

4 of 5 Dual rate spring kit August 29, 2021
Reviewer: Troy Hanson from Lake City, SD United States  
Excellent customer service. Tyler took my call on a saturday to answer a few questions. The springs made a complete different machine, how ever the instructions could use some help. This was my first time doing spring work on a rzr, and this is my 3rd.
