Wilwood's AFX 2nd Gen ProSpindle Kits contain a pair of high-strength steel spindles with a more rigid steering arm, eliminating the archaic GM factory sliding caliper mount. These spindles are engineered to simplify upgrades by directly mounting Wilwood calipers and performance disc brake kits. Improve the handling and braking of 1970-1981 GM F-body, 1975-1979 X-body, 1973-76 A-body, and 1979-90 B-body (originally equipped with 11” rotors) vehicles. A 2.00” drop lowers the center of gravity for less body roll and improved looks, without affecting steering geometry. Installs using OE ball joints with original or aftermarket control arms.

Wilwood’s AFX ProSpindle Kits contain a pair of high strength steel spindles for 1964-1972 GM A Body, 1967-1969 GM F Body, 1968-1974 GM X Body vehicles that use the original bolt on steering arms. Specifically designed for use with Wilwood’s disc brake kits, with a 2.00” drop for a more aggressive stance without affecting steering geometry. With the added benefits of providing a lower center of gravity, raised front roll center and a decreased camber change also improve handling with less body roll. Installs using the OE ball joints using original or aftermarket control arms. Kit includes four steering arm bolts, two for each spindle.

NOTE: These spindles will fit 1964-66 Buick, Chevy, Oldsmobile, and Pontiac A-body cars, but some models used steering arms with 7/16” mounting bolts. The bolt holes in the steering arm must be enlarged to .50" by drilling. It is recommended these modifications be performed by a qualified machinist.

Wilwood’s ProSpindle Kits contain a pair of Modular Spindles, steering arms and hubs assemblies for either 63-70 or 71-87 Chevrolet & GMC 2WD C10/C15 Pickups and Suburban’s. Specifically designed for use with Wilwood’s disc brake kits, with a 2.50” drop for a more aggressive stance without affecting steering geometry. Constructed from a proprietary grade of forged aluminum with an integrated modular bearing hub assembly that supports both 5 x 4.75” and 5 x 5.00” wheel bolt circles. Direct mounting for radial caliper brackets create strong, zero flex platform for brake mounting.

Wilwood's C10 Steel ProSpindle Kits contain a pair of one piece spindles and integrated steering arms for 63-87 Chevrolet & GMC 2WD C10/C15 Pickups, Blazers and Suburban's, dependent on part number. Specifically designed for use with Wilwood's disc brake kits and with a 2.50" drop for a more aggressive stance without affecting steering geometry. Constructed from a proprietary grade of cast steel with a traditional bearing snout that supports Wilwood kit specific hubs in both 5 x 4.75" and 5 x 5.00" or 6 x 5.50" wheel bolt circles.

Wilwood's C1500 Steel ProSpindle Kits contain a pair of one piece spindles and integrated steering arms for 88-98 Chevrolet & GMC 2WD C1500 Pickups, Blazers and Suburbans. Specifically designed for use with Wilwood's disc brake kits and with a 2.00” drop without affecting steering geometry. Constructed from a proprietary grade of cast steel with a traditional bearing snout that supports Wilwood kit specific hubs in both 5 x 4.75” and 5 x 5.00” wheel bolt circles.

Wilwood’s ProSpindle is specifically designed for use in fabricated A-arm suspensions on kit cars, street rods, drag cars and other custom or race applications configured around Pinto/Mustang ll suspension geometry. A redesigned one-piece forged steel body uses common Pinto and Mustang ll tie rod ends, ball joints, wheel bearings and seals. It is lightweight yet nearly three times stronger than OE or aftermarket two-piece cast iron and steel replacement spindles.

The 2" dropped spindle pin provides the desired lowered ride height without disturbing the suspension geometry. Bolt-on steering arms are strong and can be reversed to accommodate rear steer configurations. They also allow the same spindle to be used on either side of a vehicle. Bolt-on caliper brackets attach to substantially reinforced mounting bosses on the spindle body for secure, deflection-free mounting of four or six piston calipers.

Precision engineered 2” drop ProSpindle for 1955-1957 Chevy Bell Air, Nomad 210 and other full size models make installing Wilwood brakes easy. The Steel ProSpindle is lighter and stronger then the factory cast iron, while lowering the car for a better look and improved handling. Designed with reinforced attachment for a variety of Wilwood disc brake kits. Options include high performance aluminum four or six piston calipers and rotors ranging from 11.50” to 14.00” in diameter. The Pro Spindles use OE ball joints and steering arms, lowering the car with no changes to the suspension or steering geometry.
