Our F106 spindles are manufactured from billet chromoly steel and are designed for extreme-duty off-road and fabricated axle applications. These spindles are ideal for upgrading old or worn-out factory components, as well as for custom axle builds where narrowing or reconfiguring the axle is required.

These spindles maintain stock bearing sizes, seal locations, and fitment geometry, making installation straightforward while improving overall strength and durability. They are bored to clear 2 1/16” 32 spline axle shafts, allowing compatibility with larger performance axle setups used in rock bouncers, mud trucks, and Ultra4 builds.

Each spindle includes new spindle nuts for installation. Please specify in the order notes the tube ID required for your application to ensure proper fitment.

Ideal for fabricated axle housings, high-horsepower off-road builds, and competition drivetrains where factory spindle strength is not sufficient.
