QuadBoss Wheel Bearing Kit

This is a QuadBoss Wheel Bearing Kit, part number 420935. It's designed to replace the worn-out bearing in your vehicle's wheel hub, ensuring smooth rotation and proper alignment. A failing wheel bearing can cause noise, vibration, and eventually affect your steering and braking, so replacing it with a well-built kit like this is important for safety and performance.

This kit uses bearings manufactured to ABEC 3 precision levels, which means they're built to tight tolerances for high-speed operation. Inside, you'll find Chevron SRI-2 grease, which is formulated to handle a wide temperature range from -29 degrees C to 177 degrees C and includes rust and oxidation inhibitors. To keep that grease in and the elements out, the kit features triple lip rubber seals. These seals have stainless steel garter springs to ensure a snug fit against the shaft, offering solid protection against water and dirt intrusion.
