Wilwood TC6R 4.63in Register Rear Big Brake Kit - Chevrolet Silverado 2500 HD / GMC Sierra 2500 HD / Hummer H2 1999-2009

The Wilwood TC6R rear axle big brake kit replaces the factory rear disc brakes with 16.00 in SRP drilled and slotted iron rotors in a black electro coat finish and TC6 six-piston calipers in black powder coat, using staggered 1.75 in, 1.38 in and 1.38 in bores for 5.40 sq in of piston area per caliper. BP-10 compound pads and the oversized rotors are matched to the OE master cylinder output, ABS function and factory brake bias, and the kit retains the OE parking brake assembly. This version fits axle housings with a 4.63 in center register and 0.00 axle offset only, and clears many 20 in and larger wheels (verify wheel interior clearance against the wheel clearance diagram in the installation instructions before purchase). The kit supplies calipers, rotors with hats, parking brake components, bridge bolts, wear plates and a bleed screw kit; brake line kits are sold separately.
