FOX 2.0 QS3 Shocks for Polaris RZR 900 Rear

Product Description

The FOX 2.0 QS3 shocks for Polaris RZR 900 provide a major suspension upgrade for riders who want improved control, comfort, and durability on trail systems and rough terrain. Designed as a direct bolt-on replacement, these FOX Performance Series shocks improve ride quality while adding adjustable damping to help you tune the suspension for different riding conditions.

FOX Performance Series shocks replace the factory twin-tube design with a high-performance monotube shock system that provides better heat dissipation and more consistent damping performance during aggressive riding. This design prevents fade when driving through repeated bumps, rocks, and uneven terrain commonly found on tight trail systems.

The QS3 Quick Switch compression adjuster allows riders to quickly change suspension firmness using three simple settings. Switch to a softer setting for smoother trails, choose the middle setting for balanced trail riding, or increase compression damping to reduce bottom-outs when riding aggressively.

Piggyback reservoirs increase oil volume and cooling capacity, allowing the shocks to maintain consistent performance even during long rides. Combined with FOX’s velocity-sensitive damping system and durable construction, these shocks offer a significant improvement over the stock suspension.

FOX Performance Series shocks are also fully rebuildable, allowing riders to service or custom-valve them for specific riding styles and terrain.
