The Wilwood AERO4 Big Brake Rear Axle Kit (MPN: 140-9407-DR) is engineered to replace factory rear disc brakes on late-model GM trucks and SUVs. This high-capacity system is specifically designed to complement front big brake upgrades, providing the necessary stopping power for vehicles with oversized wheel and tire packages, heavy towing requirements, or high GVW. The AERO4 calipers and 14.25-inch rotors are precisely matched to the factory master cylinder output and ABS function to maintain correct vehicle bias while integrating seamlessly with the OE parking brake assembly.

• AERO4 Calipers: High-capacity four-piston calipers with a durable red powder coat finish.
• Oversized Rotors: 14.25-inch diameter drilled and slotted rotors for enhanced heat dissipation and gas venting.
• BP-10 SmartPads: Medium-friction compound provides the performance of a track pad with the low-noise and low-dust characteristics of a street pad.
• Installation: Engineered to bolt directly to factory mounting points while retaining the original parking brake function.
