Kryptonite Wheel Bearings are engineered from the ground up to handle the punishment of lifted HD trucks, oversized tires, and heavy towing. Unlike generic replacements, these hubs are built with a distinctive ball-and-taper bearing arrangement to minimize hub-face deflection—delivering tighter steering response, improved braking stability, and long-lasting reliability. Each assembly is a complete, bolt-in unit compatible with both right and left spindles on 2WD and 4WD applications, making installation straightforward with an average install time of about 2 hours. When it comes to controlling a heavy-duty truck with larger tires, every detail matters. Kryptonite Wheel Bearings are overbuilt where others cut corners—offering increased strength, better alignment stability, and extended service life. Designed for real-world abuse on and off the road, they deliver the confidence and precision serious Duramax, Silverado, and Sierra owners demand.
