New from Chassisworks – the billet-aluminum spindles and steering arms for popular GM A-, F-, and X-body muscle cars. These parts are lightweight, more rigid, and incorporate improved spindle geometry. See more details below.

Official Release:

The 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 compatiblity 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.
