STOCK SPRINGS ON WALKER EVANS SHOCKS
Walker Evans Enterprises only makes the actual shocks for Polaris vehicles, not the springs. The length and ratings are determined by Polaris. If your looking to upgrades the springs and or internals of the shocks contact us.
The most common pressure setting for RZR-1000 shocks are 125 to 150 psi. You can put them up to 200 psi as an aftermarket setting.
Most Snow Mobile shocks are set to 200 psi. Some newer models are 150 psi. The only ones that vary are Dragon Air shocks.
There is no need to check your Nitrogen unless you have a leak from your shock. If you choose to check the pressure this must be done with a no release gage. Tire gauges release pressure and will not be accurate.
