This is a true dual-rate spring kit with adjustable crossover collars from Schmidty Racing Suspensions for the Polaris RZR 900S and 1000S (2015-current). Kits are available for either 2 or 4 seat models. These kits feature top of the line Eibach brand springs which replace the low quality / saggy / poor riding OEM springs.

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

This kit will only fit the Fox Performance 2.0" aluminum bodied shocks that came standard on the RZR 900S/1000S. 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. 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.

Available Kits:

• Standard Spring Hardware: Retains the OEM pre-load collars and lower spring retainer clips, and have a billet adapter rings to fit the new Eibach springs.
• Race Spring Hardware: Replaces the tooth style OEM preload collars & wimpy cast aluminum spring retainer parts & and the "adapter ring" function from the standard hardware kit; and combines both of those functions into single, beefy pieces top and bottom, with pre-load adjustments being so much easier with the pin-style spanner pre-load collars.
