These are full replacement spring kits from Schmidty Racing Suspension for the 72" wide Polaris RZR Turbo S model with Fox Dynamix Internal Bypass (IBP) shocks.
Select Between 2018-2019 or 2020-2021 Models as the newer models have a different style rear shock body which requires different crossover rings.
The OEM springs on the shocks give a harsh ride over small bumps and begin to sag as you put miles on them. Our dual rate spring kit addresses all of these issues by delivering a
more plush and compliant ride as it flattens out jump landings and restores ride height with better bottoming resistance. This kit will not fit Walker Evans shocks.
We have done hours of testing, in a large variety of riding areas and have developed a kit that flat out works! The guesswork has been eliminated, so you can simply install the kit and ride.
With our dual rate spring kit you can expect to:
- Regain lost ride height.
- Receive a truly plush ride eliminating most of the trail chatter feedback you get from embedded rocks, ruts, tree roots, tire tracks, etc. with the lighter initial spring rate of both springs active.
- Superior bottoming resistance when the spring separator contacts the crossover collars and engages the heavier main spring solely for the remainder of the shock stroke.
Easy to follow Installation & Setup instructions (with pictures) are included, making kit installation a snap. Basic hand tools are the only required items. This kit will not fit Walker Evans shocks.
Kits Include:
- (4) Swift Tender Springs
- (4) Swift Main Springs
- (4) Upgraded Spring Separator / Sliders
- (4) Crossover Collar sets
- (1) Installation Instruction Sheet
- (4) Billet Adapter Rings For Rear Shocks to convert from OEM 3.55" springs to 3.75" Springs
