High-performance tubular control arm kit for the GM F-body and X-body chassis — 1967–1969 Camaro and Firebird, 1968–1974 Nova. Stronger than factory stamped arms, with built-in caster correction and improved geometry that lets the chassis actually use modern tires.

Lowers are 1.625" OD x .156" wall DOM tubing, uppers 1.125" OD x .125" wall DOM, with 4° positive caster built into the upper arms. Includes urethane bump stops for ball-joint protection. Lowers ride height by 1–2" depending on spring choice.
