Wilwood 140-12022-D Dynalite Front Big Brake Kit for 1965-1968 GM B-Body

Upgrade the front braking performance of your 1965-1968 GM B-Body with the Wilwood 140-12022-D Forged Dynalite Big Brake Kit. Designed for vehicles originally equipped with front drum brakes, this complete disc brake system combines a lightweight aluminum four-piston caliper with a durable iron rotor to provide confident stopping performance, improved heat management, and consistent pedal response. The kit is designed for select GM B-Body applications, including the 1965-1968 Chevrolet Impala, making it a practical performance upgrade for street-driven and custom vehicles.
The Forged Dynalite caliper features a rigid, lightweight aluminum construction with a black powder-coated finish for corrosion resistance and a clean appearance behind the wheel. Its four-piston design distributes clamping force evenly across the rotor, helping promote uniform pad wear and responsive braking. The included 12.19-inch drilled and slotted iron rotor is engineered to support effective heat dissipation and maintain braking performance during repeated stops. The rotor and caliper combination delivers a balanced blend of performance, durability, and classic vehicle compatibility.
The Wilwood 140-12022-D brake kit is supplied as a front application and is intended to replace factory drum brake components on compatible GM B-Body models. Verify vehicle year, model, wheel clearance, and installation requirements before ordering, as brake system compatibility can vary with suspension, spindle, wheel, and other vehicle modifications. With Wilwood engineering and application-specific components, this kit provides a dependable foundation for upgrading the front braking system while retaining a professional, purpose-built appearance.
