The Wilwood AERO4 rear big brake kit for Chevy 12-bolt rear applications with a 3.15-inch bearing upgrades rear braking with 14.00-inch rotors and AERO4 radial-mount calipers. It replaces factory discs while using the OE parking brake assembly and is tuned to the vehicle's ABS and master cylinder output for correct bias. High-friction BP pads and oversized rotors support heavier loads and modified wheel and tire packages.
