RZR XP Billet Rear Knuckle Set

Push the Limits—Not Your Luck

The stock rear wheel bearing carriers on your RZR are fine for casual trail rides—but when you start pushing the limits, they become a liability. Carrier flex causes premature bearing failure. If you’re hammering through the desert, deep whoops, and rocks, you need components that can keep up. That’s where the Hypertech Billet Rear Wheel Knuckle comes in.

This carrier is precision-machined from 7075-T6 billet aluminum and built to take abuse. It’s designed for serious riders who want strength, confidence, and OEM-fit reliability—all in one killer package.

Made from ultra-strong material with a 73,000 psi yield strength—nearly double that of stock 6061 aluminum.

OEM Geometry, Bolt-On Ready
Designed to match factory specs for a clean, direct-fit installation—no modifications required.

Compatible with Stock Wheel Bearings and Suspension
Works seamlessly with OEM components, so you can upgrade without overhauling your entire setup.
