This is a true dual-rate spring kit utilizing the factory crossover collars from Schmidty Racing Suspensions for the newly released Polaris Turbo R Fox Dynamix Models.


This kit will only fit Fox Dynamix X2 shocks that came standard on the Polaris Turbo R Fox Dynamix Models. This kit will not work or fit Walker Evans shocks.

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. The Turbo R spring kit install will require more tools than previous models. Our dual rate spring kits come with a detailed and complete, step-by-step installation instruction sheet with settings, diagrams, and photos.


Please include in the order comments your vehicle's setup so we can tailor the spring kit to your needs!

Full Replacement Spring Kits Include:

  • (8) Quality Swift Springs (4 tender & 4 main springs)
  • (1) Installation Instruction Sheet
  • * Each kit does all four (4) front and rear shocks*

      For X-Travel/LSK Front End Kits, ensure you select the correct option as these require different length springs for the front shocks when they are destroked for this kit.

Better Than Stock by Far

A little over a year ago, I did a complete shock rebuild for my 2022 Polaris Turbo R 4 Ultimate using MTS valving and springs installed by a certified MTS dealer. The results were very disappointing, what a waste of money. I sold my Turbo R, and purchased a 2025 Polaris Pro S 4 Ultimate (This machine is very similar to the Turbo R for 2025, with some body-style updates). I spoke with Evan a few weeks back, and he assured me that with their spring kit (no valving) I would see a noticeable difference in ride quality and performance. I will have to admit, he was right. Body roll is all but gone, gained some ride height, and ride quality has improved -- exceeding my expectations. They are not selling what all the other suspension companies are selling, this is different and that is what I was looking for. Great job SRS!

The communication and ordering from SPS is top notch. I would recommend them to all wanting to take their suspension to the next level. Ordered a spring kit, front shock forks and reservoir caps on Friday morning and received them the following Tuesday. Installation was fairly simple with the correct tools. The ride is noticeable better and should be one of the first mods on Polaris SXS’s.
