The Axiom Supply Wheel Bearing and Hub Assembly is built for professionals who demand absolute reliability from their heavy-duty trucks. Developed with a proprietary bearing and hub structure, this assembly reduces hub-face deflection under load, delivering tighter steering response and improved braking stability. Whether you are battling the stress of heavy towing, oversized tires, or a lifted suspension setup, Axiom is engineered to stay quiet and controlled under pressure. Every assembly is outfitted with Grade 10.9 zinc-plated studs and a durable ABS sensor designed to survive heat, mud, and moisture. This is a complete, bolt-in solution for 4WD platforms, arriving with the mounting hardware needed for a professional installation.
