Eibach Pro-UTV Stage 3 Spring Kit – Polaris RZR XP 4 Turbo S (Fox Dynamix)
Load your Polaris RZR XP 4 Turbo S with four passengers and gear and the factory Fox Dynamix springs start to sag — the rear squats, ride height drops, and the suspension bottoms out on g-outs and hard landings. Turbo S owners who run loaded for the desert or trail — tools, spares, accessories, full cab — feel the stock setup give up under the weight. The Eibach Pro-UTV Stage 3 Extra Load Spring Kit fixes it with a true dual-rate spring stack engineered for this chassis and its OE Fox Dynamix electronic shocks.
Stage 3 is the Extra Load (HD) tune: built for 4-seat setups carrying four riders plus 100-199 lbs of additional weight, it holds ride height under load, sharpens control, and resists bottoming without touching your shock valving. Eibach develops every Pro-UTV system through chassis-specific testing — no revalve required, just a bolt-on spring swap.
