Why the Pro S 4 Seater's Fox Shocks Need a Tender Spring Upgrade

The RZR Pro S 4 Seater is built for serious performance with a wider stance and Fox shocks that deliver genuine capability. But even Fox shocks are limited by their spring rate. The factory single-rate spring is tuned for a broad range of loads and conditions — a compromise that's too stiff for light loads on smooth trails and not progressive enough for big hits with a full crew at speed.

A tender spring adds a softer secondary spring in series with the main coil. At low shaft speeds and small bumps, only the tender spring compresses — giving all four passengers a plush, compliant feel. As forces increase with a full load or bigger hits, the main spring engages and provides the support needed. The result is a suspension that feels soft on small chop but firm when you need it, with 2-3" more ride height to clear obstacles and run larger tires.

"Bought the full kit in Black and it looks and performs great. The ride quality improvement is real and my Fox shocks finally feel like they're working the way they should with a full crew."
