Product details

This Wilwood front drag conversion uses four-piston Dynalite calipers, drilled steel rotors and replacement aluminum hubs for the specified GM spindle arrangement. The solid friction rings measure 10.75 × 0.35 inches. Its vehicle coverage includes rear-wheel-drive cars and selected compact trucks using the required mounting geometry. 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

Compare the exact model/year and two-wheel-drive conditions in the table, including the S10/S15, Sonoma and related applications. DS196 identifies the G-body spindle arrangement and the required original-spindle modifications. Account for the +0.59-inch wheel mounting change before checking tire position. Hydraulic lines are separate, and the actual wheel profile must be compared with the brake-clearance template.

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