Our 40 spline 14 bolt 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 are made to use with 40 spline axle shafts while still maintaining a 14 bolt style hub. Larger outer bearings are required when using these spindles, while the inner bearings and seals maintain factory part numbers.

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.

Spindles are sold individually.
