Strengthen your vintage VW with modern connections. This kit allows Mk1, Mk2, and Mk3 rear stub axles to accept the much sturdier Mk4-generation wheel bearings. These parts are sourced via the 9N Polo platform (which bridges all the other chassis).
Precision engineered and easy to install, this upgrade delivers improved durability, smoother rolling, and the confidence to push harder—whether street driving or tracking your retro build. USRT specifically endorses this modification for improving rally cars that will slide sideways (incurring tremendous side loads).
Compatible with original VW beam rear ends. Street-legal performance meets OEM+ perfection. You get both stub axles, two rear unit bearings, plus a pair of Polo 4x100 solid rear brake rotors. Want even more? Combine with our LIGHTWEIGHT Rear Caliper Upgrade, of course. Let's STOP IT!
