Wilwood AFX ProSpindles 2″ Drop 831-15890



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.
