The Eibach Pro-UTV Stage 3 kit (part E85-209-012-03-22) replaces the coil springs on a factory coilover setup and keeps the existing shock bodies. It is a true dual-spring setup that includes springs, hardware and setup instructions, and the manufacturer says no revalve is required. The manufacturer positions the kit for four-seat RZR XP 4 Turbo models carrying four riders plus up to 100-199lbs of additional weight, and it is made by Eibach in the U.S.A., with a limited lifetime warranty.
Compared with stock springs, the kit provides a more controlled ride with less bottoming resistance, smoother bump compliance, and better handling over rough terrain, according to a review posted on user forums. Owners who fit it to heavily loaded four-seaters report that the ride quality gain justifies the cost, and the alternative of buying a full aftermarket shock package is far pricier. Fitment is listed by the manufacturer as 2018-2021 RZR XP 4 Turbo with Walker Evans OE shocks, so confirm your model year and shock type before ordering.

The manufacturer labels this kit as a Stage 3 extra load system for Walker Evans OE shocks. Its Fox Dynamix kits are separate part numbers, so verify the shock type on your RZR before ordering.
No. Owners on user forums say the kit installs over the factory shock bodies and hardware, so the shocks themselves stay in place.
Owners on user forums say an average set of hand tools, a jack with jack stands, and a safe spring compressor are sufficient.
Installation is moderate in difficulty and is manageable for anyone who has previously removed the shocks. Owners on user forums say no shock disassembly is required, and the manufacturer includes setup instructions with baseline shock settings. Set ride height and preload using Eibach's specified baselines rather than the factory service manual method, since owners note that method does not account for aftermarket springs and added payload. One owner reported that the rear sliders needed light fitting with sandpaper, so check slider fit before final assembly.
