The Wilwood AERO4 rear big brake kit for Chevy 12-bolt rear applications is built around 14.00-inch rotors and red AERO4 calipers, specified for hubs with a 3.15-inch bearing. It replaces factory discs while retaining the OE parking brake assembly and is matched to master cylinder output and ABS to preserve bias. High-friction BP pads and oversized rotors increase stopping capacity and durability for heavier or modified vehicles.
