Axle Fitment & Brake System Compatibility

Proper axle housing identification is essential when selecting a rear disc brake conversion kit. Although these kits are designed for Ford 9-inch rear axle applications, not all Ford 9-inch housings use the same flange dimensions or axle offsets.

The kits listed in this category are designed for the Big Ford New Style housing flange with a 2.50-inch axle offset. Before ordering, confirm the housing flange bolt pattern, axle bearing configuration, axle offset, wheel bolt pattern, and wheel clearance. The parking brake cable arrangement and hydraulic brake system must also be considered when planning the installation.

Additional components such as brake hoses, parking brake cables, hydraulic fittings, and master cylinder or proportioning valve upgrades may be required depending on the vehicle and existing brake system.
