Eibach Pro-UTV Stage 2 Spring Kit – Polaris RZR XP 4 Turbo S (Fox Dynamix)
Push your Polaris RZR XP 4 Turbo S hard and the factory Fox Dynamix setup starts to feel vague — the chassis bucks through choppy sections, rolls in the corners, and gets unsettled when you add a passenger and gear. Turbo S owners who ride aggressively or run loaded feel the stock springs lose composure right when control matters most. The Eibach Pro-UTV Stage 2 Performance Spring Kit fixes that with a true dual-rate spring stack engineered for this chassis and its OE Fox Dynamix electronic shocks.
Stage 2 is the Performance tune: built for 2-4 riders and up to 99 lbs of additional weight, it improves suspension progression, reduces buck, and sharpens control through g-outs and rough terrain without changing your shocks. Eibach develops every Pro-UTV system through chassis-specific testing — no revalve required, just a bolt-on spring swap.
