Brake Kit Rear Chevy 12 Bolt 2.81in Offset

Upgrade the rear braking performance of your GM vehicle with the Wilwood AERO4 Big Brake Kit, Part Number 140-10943-DR. Designed for Chevy 12-bolt applications with a 2.81-inch offset, this complete rear brake system combines a lightweight aluminum four-piston caliper with a large drilled and slotted iron rotor for improved stopping power, heat management, and consistent performance under demanding driving conditions. The caliper features a durable red powder-coated finish that adds a distinctive appearance while helping protect the component from corrosion and wear.
The AERO4 system is engineered for enthusiasts seeking a balanced combination of braking control, reliability, and reduced unsprung weight. The rotor’s drilled and slotted design helps promote cooling and provides effective friction-surface cleaning, while the multi-piston caliper delivers even pad pressure across the rotor. This configuration supports confident braking response for street-driven performance vehicles, custom builds, and other GM applications using the specified rear 12-bolt setup.
Designed as a complete rear brake kit, the Wilwood 140-10943-DR provides a purpose-built upgrade over many original equipment braking systems. Verify vehicle compatibility, wheel clearance, axle configuration, and installation requirements before purchase. Professional installation is recommended to ensure proper alignment, hydraulic connection, bedding, and final brake-system operation.
