2011-2019 Duramax HD Wheel Bearing Assembly (AX515145)

The Axiom Supply wheel bearing assembly is a complete bolt-in hub unit built for heavy-duty 2011-2019 Duramax HD trucks. A proprietary bearing and hub structure reduces hub-face deflection under load for tighter steering, improved braking stability, and added durability when towing, running oversized tires, or a lifted setup. Each unit fits both left and right spindles and installs in roughly two hours with no modifications.
