FORD 9", ø330mm, C6 Z51

The KORE3 ø330mm Rear Big-Brake Kit for the venerable Ford 9" rear axle applications adapts high-performance, high-quality, 5th or 6th generation (C5/C6) Corvette brake components to your Ford 9" equipped vehicle.

Take advantage of the vast aftermarket support for both the Ford 9" and the C5/C6 Corvette brakes by combining the best of both worlds. Numerous rotors, calipers, and brake pads are available to suit nearly anybody's needs and/or budget, making the KORE3 Ford 9" big-brake conversion a nearly unbeatable combination for the rear of any muscle car, whether you're grocery getting, pro-touring, or a little bit of both.

Both Ford and the aftermarket offer several versions of the 9" housings with the most common described below. Dimensions represent H X W X Offset where H=Vertical Hole Separation, W=Horizontal Hole Separation, and Offset=Distance from Axle Shaft Flange to Outside of Bearing.
