Wilwood Front 11-Inch Dynapro Dust-Boot Brake Kit for GM and Ridetech Pin Spindle Applications, Black

This 11-inch front conversion supplies dual-pattern hubs, vented iron rotors and black Dynapro dust-boot calipers. The application list combines specific factory GM spindles with vehicles using Ridetech pin spindles, so the installed spindle determines the usable configuration.

Fitment & Compatibility

Use DS998 to distinguish the applicable disc, drum or aftermarket spindle. Some early drum spindles need modification; wheels with a mounting pad wider than the hub face require the specified spacer, while stamped steel wheels may need a hub shield.

Documented model groups, subject to each year, submodel and spindle/axle qualification: Ford Falcon, Mustang, F-100; Mercury Comet; Chevrolet Chevy II, Corvette, Chevelle, El Camino, Malibu, Camaro, Nova, Monte Carlo; Buick Skylark, Special, Sportwagon, Gran Sport, GS 350, GS 400, GS, GS 455, Apollo; Oldsmobile 442, Cutlass, F85, Vista Cruiser, Cutlass Supreme, Omega; Pontiac Acadian, Beaumont, GTO, LeMans, Tempest, Firebird, Grand Prix, Ventura; GMC Sprint.

Drum Brake Spindles; Drum Brake Spindle w/o O.A.I.

The installation reference distinguishes wheel-pad overhang from a supported stamped steel wheel. Overhang requires a 0.20-inch-thick steel spacer, 6.60 inches in diameter, part 300-11961 (listed in the installation parts list). A stamped wheel without overhang should instead use the separate 0.09-inch-thick, 6.15-inch-diameter shield 300-10716.

Flexible brake lines are not included. Original lines are not assumed to connect to the Wilwood calipers; select the application-specific or correctly sized universal hose and matching fittings.

Universal Flexline kits available: 220-7056 (14"), 220-7699 (16") or 220-8307 (18"). Choose correct length for your application.

An independently added universal parking-brake cable system may require cable or vehicle modifications. It is separate from this front service-brake kit.
