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 Swift 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 Swift 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.
ON 2023 MODELS, MAKE SURE WHEN SELECTING THIS OPTION THAT YOUR VEHICLE CAME FROM THE FACTORY WITH CROSSOVER RINGS AS THIS OPTION DOES NOT INCLUDE THEM.
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.
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.
