Product details

For a five-lug Large C10 flange, this rear kit pairs red calipers with GT slotted rotors and BP-10 pads. The 12.88-inch discs have 48 curved cooling vanes, and their parking-brake hats are configured for the 2.42-inch axle offset. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its components include calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to suit the complete brake system.

Fitment & Compatibility

For five-lug Chevrolet/GMC applications using the Large Chevy C10 rear flange and 2.42-inch axle offset. The complete table separates pickup, Suburban, Blazer, Jimmy and van applications by year and equipment; it does not override the five-lug and flange requirements. Verify the axle register, flange diameter and stud pattern using the drawing. Internal parking shoes are included; cables, clevis hardware and flexlines are separate. Universal cable routing may require modification. Select 14-, 16- or 18-inch flexlines to suit the actual installation. Nominal minimum wheel diameter: 17 in; 431.8 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.
