This is a true dual-rate spring kit with adjustable crossover collars from Schmidty Racing Suspensions for the Polaris PRO XP Premium/Sport and PRO XP4 Premium/Sport with Fox Non-Live Valve Shocks. Our spring kits feature top of the line springs which replace the low quality / saggy / poor riding OEM springs. Ask our competitors what springs they use as many will not be able to claim using reputablesprings. 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.
This kit will only fit Fox Non-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.
We use high quality springs in our kits, because they are the best! While these may not be the cheapest spring, we want to provide you with the best possible kit when you go to upgrade your ride with replacement springs. Our R&D backed spring rates, 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.
We encourage you to ask our competitors what springs they are using in their kits!
