Our 05+ Ford Super Duty Unit Bearing Cups are engineered for extreme-duty fabricated axle builds and off-road competition applications. Designed to integrate 2005+ Ford Super Duty unit bearings into custom axle housings, these weld-on cups eliminate the need for traditional spindle setups while allowing for larger spline axle configurations and simplified high-strength drivetrain packaging.

Machined in-house for precision fitment and maximum durability, these unit bearing cups are ideal for rock bouncers, mud trucks, Ultra4 cars, and heavy-horsepower off-road builds where traditional hub and spindle assemblies are not suitable.

Common applications include fabricated front axle housings, spindle delete conversions, custom Dana 60 builds, and high-performance off-road racing axles.

Cups come in 3.5” and 4.0” bores. Additional sizes can be made upon request.
