Pro R 4 owners who run loaded for the desert or the trail — spare tires, tools, coolers, full cab — feel the stock springs sag 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 DV electronic shocks.\u003c\/p\u003e\n\u003cp\u003eStage 3 is the Extra Load (HD) tune: built for 2-seaters with two riders and 4-seaters with four riders plus 150-200 lbs of additional weight, it holds ride height under heavy loads, 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.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eWho Is This Kit For?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRZR Pro R 4 Ultimate owners who routinely run four-up with gear.\u003c\/li\u003e\n\u003cli\u003eRiders carrying 150-200 lbs of added weight — spares, tools, armor, camp loadout.\u003c\/li\u003e\n\u003cli\u003eOwners fighting rear squat, lost ride height, and bottoming under heavy loads.\u003c\/li\u003e\n\u003cli\u003eAnyone who wants HD load control while keeping the factory Fox Dynamix shocks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eCommon Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDesert running and high-speed whoops fully loaded with passengers and gear.\u003c\/li\u003e\n\u003cli\u003eOverland and hunting trips with heavy cargo and recovery equipment.\u003c\/li\u003e\n\u003cli\u003eTrail riding four-up where the factory springs sag and bottom.\u003c\/li\u003e\n\u003cli\u003eRestoring ride height and bottom-out resistance on a frequently loaded Pro R 4.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTrue dual-spring setup engineered specifically for the Polaris RZR Pro R 4 Ultimate.\u003c\/li\u003e\n\u003cli\u003eStage 3 Extra Load tuning for 150-200 lbs of additional weight plus four passengers.\u003c\/li\u003e\n\u003cli\u003eHolds ride height under load, improves stability and bottom-out resistance.\u003c\/li\u003e\n\u003cli\u003eIncreases ground clearance, reduces buck, and maximizes control over g-outs and rough terrain.\u003c\/li\u003e\n\u003cli\u003eSet of 8 springs with setup instructions for an easy bolt-on installation.\u003c\/li\u003e\n\u003cli\u003eNo revalve required — works with the OE Fox Dynamix DV electronic shocks.\u003c\/li\u003e\n\u003cli\u003eRace-proven durability, quality, and consistency.
