After years of testing, development and a decade on the market, RT Pro has proven to have the best replacement spring options for today’s UTV’s. This kit is for the Polaris RZR XP4 1000 (4 seat) using OEM Walker Evans shocks. This dual rate kit gives a substantial improvement in ride quality while improving handling and stability as well at G-out resistance. We’ve found the perfect combination of spring length to rate ratio and are very happy with our results. This kit is for all four corners of the machine.
The spring kit alone can make a night and day difference in the performance of the RZR. This is enough of an improvement most recreational driver’s will never need to make any other internal adjustments to the shocks and will be able to fine-tune the ride with the external adjustments provided on the OEM shocks. For the customers wanting more, contact Yokley Racing for custom valving. Note: RT Pro does not offer valving service nor do we handle the shocks for Yokley Racing. For revalving services please contact them directly.
We found there really only needed to be two rate kits needed for the 4 seat model. The Standard rate kit works great for 2-4 people without a ton of extra gear loaded beyond what the average owner takes with them for a day on the trail or dunes. The Heavy Duty kit is recommended when carrying 4 people and a lot of gear most often.
This kit fits all 2014+ RZR XP4 1000 4 SEAT models using OEM Walker Evans shocks. This kit will also work on any aftermarket 2.0″ front / 2.5″ rear shock application.
Kit includes (8) springs, (4) spring spacers and 4 front spring adapters. All springs come with silver powdercoat.
This kit is 100% MADE IN THE U.S.A.
