The ABR Wheel Hubs were engineered, designed, and manufactured to replace worn or damaged O.E.M. components with superior durability and longer life. The quality matches or exceeds the O.E.M. components at a more economical cost. Cast aluminum or iron to match O.E.M. materials. Includes bare hub without studs (stud kits available separately). Reduces looseness in the wheel assembly caused by wear, even after new wheel bearing installation. Restores tolerances and reduces play on bearing mating surfaces. Replacing bent or damaged hubs restores that factory-smooth ride.
