These 1967-69 Chevy Camaro and Pontiac Firebird tubular control arms are now powdercoated, include bump stops and have improved ball joint clearances. Our tubular upper and lower tubular control arm set is great way to improve front end strength and handling by offering less deflection than factory stamped units. Special cam plugs allow for more caster adjustment, giving vehicle more high speed stability. Works with stock coil springs or coil over shocks
