Why does my Polaris RZR buck in the rear?

The notorious Polaris RZR rear-end bucking is caused by a deficiency in the factory shock rebound damping and mismatched spring rates. MTS Off-Road fixes this permanently using proprietary internal valving changes and custom dual-rate spring kits tailored to your exact machine weight.

Shock Reservoir Caps

Leaking reservoir caps are one of the most common causes of side-by-side shock failure, and one of the easiest to prevent. Nitrogen escapes, pressure drops, the oil cavitates and the shock starts destroying its own seals from the inside.

Our Schrader valve caps let you check and top off pressure yourself in minutes instead of guessing. High volume caps go further — more nitrogen volume means more consistent damping and less fade on long, fast desert runs.

Available for Fox 2.5 reservoirs and Walker Evans 2.0 and 2.5. Genuinely the cheapest insurance on this site.
