Product Description

PowerStop KC8670B-36 is a Z36 Extreme Truck & Tow front brake upgrade kit designed for the 2020-2021 Chevrolet Silverado 3500 HD. The complete package combines 355 mm cross-drilled and slotted cast-iron rotors, carbon-fiber ceramic brake pads, and red powder-coated two-piston replacement calipers to provide enhanced braking capability for demanding truck applications.

The Z36 carbon-fiber ceramic pads are engineered for the increased heat and load associated with towing, hauling, mountain driving, and off-road use. The drilled and slotted rotors help manage heat, while their silver zinc plating provides corrosion resistance. Stainless-steel shims contribute to quieter operation, and the replacement calipers provide a durable, performance-oriented finish.

This kit uses a direct bolt-on installation and includes the required mounting hardware. It is specifically cataloged for 2020-2021 Chevrolet Silverado 3500 HD models with the specified 8-lug front brake configuration. Verify the truck's original brake configuration before installation.
