Fitment:

For "Old-style" big bearing 9" Ford axle
For "New-style" big bearing 9" Ford axle
For Axle housings with minimum axle offsets of 2-3/8" to 2-1/2"

！！！NOTE：

NOT work on pickup housings or the 50's 9" housings as they only have about 2" backspace. The exception would be the late 50's station wagon rear ends.

Fits Ford 9 Inch Housings

This disc brake kit fits Ford 9 inch axles, as well as passenger car Ford 9 inch axle housings with “big bearing” ends (3.150” O.D. bearing, found on passenger cars from 1974-79). Included bracketry will adapt this kit to both “new style” and “old style” Ford 9 inch housing flanges with the 3/8” bearing retainer bolt holes. Bracket spacers are also included, allowing this kit to work with axle flange offsets of 2-3/8” or 2-1/2” common on Ford 9 inch passenger car rear ends. Axle flange offset is measured from the axle housing flange face (with bearing retainer removed) to the axle shaft flange face (side where the brake rotor/drum rides, including the thickness of the axle flange).

Hardware and Instructions Included

Kit includes a detailed, step-by-step instruction sheet with images. The floating calipers include new Grade 5 slider bolts, with all remaining hardware of Grade 8 quality. Cast iron rotors feature a dual bolt pattern in 5x4.5” (Ford/Mopar/AMC) or 5x4.75” (Chevy/GM) to match your desired wheel hub pattern. Plus, this assembly will clear most 15” diameter wheels designed with disc brakes in mind. Note that there are no provisions for a parking brake, making this the perfect disc brake conversion kit for the budget-focused builder who prefers a basic upgrade kit.

• Disc brake stopping power at nearly the same cost as rebuilding/replacing drum brakes
• 11-1/4” diameter, 1” thick vented cast iron rotors dissipate heat faster than drum brakes
• Serviceable design ensures good drivability and piece-of-mind when on the road
• Street-friendly GM D154 style pads, replacements available nearly everywhere
• GM “Metric” style single piston calipers with 7/16”-20 banjo-style inlets
• Fits Ford “big bearing” 9 inch housings from passenger cars
• Use with Ford 9 inch rear ends with 2-3/8” or 2-1/2” axle flange-to-housing offsets
• Dual wheel bolt patterns covering all GM/Ford/Mopar (5x4.5” for 1/2” studs, 5x4.75” for 7/16” studs)
• Use with 15” or larger disc brake-style wheels
• Easy bolt-on installation w/ included instruction sheet
• Includes heavy steel mounting brackets, Grade 8 hardware and nylock nuts (everything you need)
• Installation Tips

1. For passenger car axles only, 15” and larger wheels only
2. Fits 9 inch housing axle offsets of 2-3/8” to 2-1/2” (measured from outside of housing flange to outside of axle flange, not measured out to axle register but only surface where the rotor sits against). Requires “big bearing” housing ends (for a 3.150” O.D. bearing) with 3/8” bearing retainer bolt holes.
3. Brake rotor has a 2.78” center hole and works with axle shaft flanges no larger than 6-1/4” diameter. If your axle shaft flange exceeds that diameter, you will need machine the flange to decrease the diameter.
4. This kit is an aftermarket solution. It is not intended to be a direct installation or OEM replacement. Due to changes in production in certain years, your application may require modifications beyond these instructions for this kit to install properly.
