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 rate which allows us to custom tailor our long springs, (which determines the final rate of the suspension) to each individuals needs.
RATES
We found there really only needed to be two rate kits needed for this model. The Standard rate kit works great for 2 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 2 larger people and a lot of gear most often. For the best ride combine springs with our 2" lift kit available as a discounted Bundle HERE. The lift kit will allow you to run less preload for a smoother ride so even if you don't necessarily want more height, the lift kit also works as a geometry improvement for more stability and better ride/handling. Use our simple Spring Rate Calculator above to calculate the best ride for you.

REVALVING
In over a decade of selling OEM replacement springs we've found our kits are more than enough for 80% off all UTV owners to be completely happy with their suspension. For the remaining 20% we recommend revalving or completely new shocks. The 20% is made up of extremely hard drivers who spend a lot of time in their UTV either racing or riding hard every weekend. For the average trail rider who goes once or twice a month revalving really isn't needed with our springs. Unlike any other kit on the market, our kits are designed to optimize the OEM valving.
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 on the track or the trail. We've tried a lot of "shock guys" and William is who we trust. He will get you what you need at a very fair price. For William's contact info feel free to message us through our contact page and we'll get you connected.
