FORD 9", ø340mm, C6 Z06

The KORE3 ø340mm Rear Big-Brake Kit for the venerable Ford 9" rear axle applications adapts high-performance, high-quality, 6th generation (C5/C6) Corvette brake components to your Ford 9" equipped vehicle.

This ø340mm C6 Z06 kit is designed to be used in conjunction with similar front C6 Z06 kits. The calipers and rotors are massive and make a visual statement like no other for the money. There is vast aftermarket support for C6 Z06 Corvette rotors and brake pads to suit nearly anybody's needs and/or budget, making the KORE3 big-brake conversion a nearly unbeatable combination for the front and 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.

  • Small-Bearing (ø2.835"): 2.00 X 3.31 X 2.66
  • Big-Bearing (ø3.150"): 2.38 X 3.50 X 2.36
  • Big-Bearing Torino (ø3.150"): 2.00 X 3.56 X 2.50

  2. Standard rotor configuration is 5 x 4.75" with ø70.5mm center pilot (GM). Alternative rotor configurations are available. Please contact for details.

  3. Axle flanges may need to be machined to be less than ø5.9" outside diameter to properly mate with rotors.

  4. Minimum ø18" wheels are recommended, however not all ø18" wheels will fit. Verify wheel fitment prior to ordering using the appropriate KORE3 fitment template.

The C6 Z06 calipers can be coverted from one hand to the other by swapping the bleeders and the cross-over tubes. The brackets are ambidextrous and can be installed facing forward or rearward, inline with the pinion.
