Wilwood Rear 12.19-Inch Plain-Rotor Parking Brake Package, Red, Chevrolet / GMC C1500 (1988–1998)

Wilwood configures this rear Dynalite kit around 12.19 × 0.81-inch rotors for Chevrolet / GMC C1500 (1988–1998). The selected red calipers use 4 service pistons each; matching the factory or specified conversion hardware is essential to the complete installation. Camarillo, California is home to Wilwood Engineering, founded in 1977 by Bill Wood. The company designs and manufactures disc-brake systems for motorsport, street-performance and specialized applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must match the complete braking system.

Fitment & Compatibility

For the five-lug 1988–1998 Chevrolet and GMC C1500 axle flange documented in DS1563. Verify the housing pattern, 3.25-inch measured axle offset and the specific wheel clearance. The supplied internal parking-brake assembly uses the OE cable only after modification with the included cable-end adapter kit.
