FITMENT AND COMPATIBILITY

This park brake kit is designed for applications using Big Ford axle flanges. Confirm the axle housing flange pattern, wheel stud pattern, and a 2.80" axle center register diameter for proper fitment. The kit is built for a 2.36" axle offset, the distance from the wheel side of the axle flange to the housing. For increased durability, especially when running larger wheels, upgrading from OEM 7/16" studs to 1/2" studs is recommended.
