Chris Alston’s Chassisworks – Billet-Aluminum GM Spindles

GM Spindles

Chassisworks’ billet-aluminum spindles and steering arms are direct-replacement components for popular GM A-, F-, and X-body muscle cars from 1964 to 1972. While maintaining compatibility with the factory lower control arm, and most aftermarket control arms and brakes, improvements to the spindle geometry are incorporated. Chassisworks used the latest analysis software to develop a superior to steel spindle, that is much more rigid and lighter weight. The resulting increase in suspension geometry control is substantial.

Not limiting you to a particular vehicle stance, Chassisworks manufactures 2”-drop and stock-height uprights. Overall height of both upright versions is 1-1/2” taller than stock, resulting in more aggressive camber gain with increased cornering ability. Chassisworks offers two versions of lightweight billet-aluminum steering arms; bumpsteer-corrected for the A-body platform and Z28 quick-ratio for F- and X-Body platforms.

Spindles and steering arms feature a sleek black-anodized finish. Heat treated, corrosion resistant, slotted flange nuts are included, 1/2-20 for upper and 9/16-18 for lower balljoints, with optional 5/8-18 for oversize stud lower balljoints.

Note: Taller spindle height requires Chassisworks billet steering arms and aftermarket upper A-arm to properly position balljoint range of misalignment.
