Eibach Pro-UTV Stage 4 HD Spring Kit – Polaris RZR XP 4 1000 (Walker Evans)
Run your 2024-2026 Polaris RZR XP 4 1000 four-up with a fully loaded, accessory-heavy build and the factory Walker Evans springs simply can't keep up — the rear sags hard, ride height collapses, and the suspension blows through its travel and bottoms on g-outs. XP 4 1000 owners hauling four passengers plus 300+ lbs of gear feel the stock setup overwhelmed. The Eibach Pro-UTV Stage 4 HD Performance Spring Kit fixes it with a true dual-rate spring stack engineered for this chassis and its OE Walker Evans 1000cc shocks.
Stage 4 is the heaviest-duty Extra Load tune: built for 4-seat machines running four riders and 300+ lbs of additional weight (and 2-seat machines loaded with gear), it restores ride height, sharpens control, and resists bottoming under the heaviest loads without touching your shock valving. Eibach develops every Pro-UTV system through chassis-specific testing — no revalve required, just a bolt-on spring swap.
