Wilwood 14-Inch Drilled Front Hub Conversion for Second-Generation AFX ProSpindles, Black AERO6 Calipers, Listed GM Vehicles

Drilled and slotted front rotors, black AERO6 calipers and hubs suit listed GM vehicles using second-generation AFX ProSpindles. Check wheel offset. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. The company designs and manufactures disc brake systems and components for motorsport, street-performance and specialized use. Calipers, master cylinders, brake rotors, valves, brake lines and fittings form its range; the complete brake system determines which individual components are suitable.

Fitment & Compatibility

Only the specified second-generation Wilwood AFX 2-inch drop ProSpindle is the intended hub interface; this is not a stock-spindle conversion. DS-1432 identifies ProSpindle kit 831-15958, purchased separately. The full application chart below identifies the vehicle and chassis combinations that use that spindle. The +0.65-inch hub change moves each wheel outward relative to the catalog comparison, so assess tire-to-fender space as well as caliper-to-wheel clearance. Supply suitable hydraulic hoses separately and match the front and rear brake balance.
