Fitment & Compatibility

Match the actual Big Ford flange, 2.36-inch offset and 5 x 5.50-inch wheel pattern to DS1018. Provide the appropriate hydraulic lines and parking-cable adaptation separately.

The hat and axle interface need three independent checks: the housing-end pattern, the specified offset and the illustrated 2.88-inch register/centering arrangement. Flange diameter is limited to 6.61 inches; the drawing also calls for a 45-degree chamfer measuring 0.050 inch.

The installation reference identifies Big Ford Bronco rear applications with 3300-lb axle/11-inch drums for 1966–1975 and the listed 1976–1977 configurations. Verify the actual flange,2.36-inch offset and axle register.

Hydraulic hoses/fittings and parking-brake cables, adapters and cable hardware are not included. Choose a compatible cable arrangement for the internal parking brake; universal cable systems may require vehicle or cable modifications.
