TC6R rear axle disc brake kits with 16” rotors are the ultimate big brake solution for highly customized and modified trucks or SUV's upgraded to larger than stock wheels. TC6R kits can fit many 20”and larger wheels (Verify your wheel interior clearance to the wheel clearance diagram in the installation instructions before purchase). TC6R kits replace the factory disc brakes and use the OE parking brake assembly as a compliment to front big brake upgrades. TC6R calipers, BP-10 compound pads, and oversized rotors are matched to the OE master cylinder output, ABS function, and individual vehicle bias requirements of each vehicle. These combined enhancements provide the necessary control over big wheels and tires to provide safe stopping on heavy weight vehicles.
