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.
