Built for trucks that work hard and refuse to quit, the Axiom Supply Wheel Bearing and Hub Assembly delivers confidence where it matters most. A reinforced hub and proprietary bearing design minimize deflection under heavy loads, translating to sharper steering feel and stronger braking control. Whether you are towing, running oversized tires, or putting your Super Duty through demanding daily use, this assembly is engineered to keep everything tight and predictable. Axiom units utilize precision tapered roller bearings packed with high-performance grease. Every assembly is outfitted with Grade 10.9 zinc-plated studs and a durable ABS sensor designed to survive heat, mud, and moisture.
