The Wilwood AERO4 rear big brake kit for Chevy 12-bolt rear applications with a 3.15-inch bearing features 14.00-inch drilled rotors paired with AERO4 radial-mount calipers to improve rear stopping power. Designed to replace factory discs while retaining the OE parking brake assembly, the kit is matched to ABS and master cylinder output and uses BP compound pads for higher friction and added durability under increased braking demands.
