The Wilwood AERO4 rear parking-brake axle kit uses radial-mount AERO4 calipers and oversized 14.00in rotors to replace factory discs and incorporate the OE parking brake assembly, providing a balanced rear upgrade to front big-brake systems. Matched to OE master cylinder output and ABS function, the kit increases braking capacity and durability while contributing modern styling that complements wheel, tire, and suspension upgrades on late-model performance builds.
