The RZR XP Turbo 4 Seater carries more weight than a 2-seat machine — more passengers, more gear, more stress on the suspension. The factory single-rate Fox spring is tuned for a broad range of loads and conditions, which means it's always a compromise: too stiff for light loads on smooth trails, 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.
"My XP Turbo 4 seater is our group ride machine and this kit transformed it. Everyone in the crew noticed the difference immediately — smoother, more controlled, and the extra height is great for bigger tires. Easy install."
"Bought the full kit in Velocity Blue to match my build. The ride quality improvement is real — my Fox shocks finally feel like they're working the way they should with a full load of passengers."
