This spring kit gives a substantial improvement in ride quality while improving handling 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. After a lot of testing, it was determined there is no need for a dual-rate spring setup on the front of a RZR 900 XC. We decided to stay with the proven single rate spring setup we've been using for years on the fronts of the narrower RZR's. The rear however has found large improvements by switching to a dual-rate combination.

These springs are replacements for the OEM springs on the OEM Fox shocks. We provide a short spring, a long spring and a delrin spacer for each rear shock. The secret is in our short springs. We've found a perfect universal rate which allows us to custom tailor our long springs, (which determines the final rate of the suspension) to each individuals needs. We have narrowed it down to two options; Medium and Heavy. The medium set is a perfect improvement over stock for recreational drivers without very much extra weight added to the vehicle. The heavy rate is perfect for the aggressive driver, intermediate racer or for a vehicle with some extra weight in accessories or passengers. Of course because we can make all the adjustments with one spring per shock we are able to sell individual long springs to people looking to "tune" there springs sets in to their specific liking. We list the two standard packages which will cover about 90% of all users. If you would like to discuss a custom combination feel free to call and an engineer can help you find what you need.

NOTE: None of these options will fit an aftermarket 2.0" shock. If you have aftermarket shocks and want our spring kit we can do this for you if you call your order in.

RT Pro springs are the ONLY high quality replacement springs made in the U.S.A.!


For the ultimate performance from the OEM shocks, add these springs and contact William Yokley of Yokley Racing in Kentucky for revalving. William has been building shocks for years and knows how to make them work for each application. He's a 5 time GNCC national champion UTV racer and also has a WORCS UTV championship as well as many other racing successes to back up his knowledge and ability to make a UTV work right. We've tried everyone else and have found most of them to be selling "snake oil". William will get you what you need at a very fair price. After having him rework some of our shocks we will never go to anyone else. This isn't a full time business for him so he doesn't need to sell you anything to put food on the table like most other guys! For William's contact info feel free to message us through our contact page and we'll get you connected.
