Product details

Red Superlite calipers clamp vented Spec-37 rotors in this Wilwood rear truck package. The 12.88-inch drilled/slotted friction rings mount to hats that also contain the parking-brake drum. This is the large-Chevy-end, 2.42-inch-offset version, so the axle's physical dimensions control its selection. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Check the exact Chevrolet/GMC application and any rear-housing changes before installation. The list includes both original and modified vehicle configurations, but a front drop-spindle description does not identify a rear flange. Measure the bearing register, stud pattern and offset directly. Suitable hydraulic lines and parking-brake cables are separate, and the wheel must clear both the caliper face and the rotor circumference.

Match the individual model, year, submodel and brake configuration in the fitment table below.
