Mastodon Tubular Control Arm Kit GM A-Body 1968-72 Chevelle GTO

Tubular upper and lower control arms for the GM A-body platform — fits Chevelle, El Camino, GTO, Cutlass, Skylark, 442, Tempest, and LeMans from 1968–1972. The single most-bolted-on upgrade for this platform: stronger than factory stamped arms, less deflection, and the geometry corrections needed once you start running modern tires and lowered ride height.

Uppers run 1.125" OD x .125" wall DOM tubing, lowers 1.625" OD x .156" wall DOM, with greaseable bushings throughout. Built-in +4° positive caster on the uppers gives the modern tire footprint your factory arms can't.
