Designed for the specific needs of drag racing, QA1 GM 2.0 drag racing control arms are bolt-in upgrades to the original suspension or outdated tubular control arms. Besides improving overall handling, ride quality, and vehicle stance, these arms improve factory suspension geometry and pave the way for planning additional upgrades. The increased positive caster design improves straight line stability. QA1 arms are compatible with OE-style sway bars and come with droop stops on the upper arms with bump stops on the lowers. The droop stops are adjustable to enable the perfect front-end rise for optimized launches. These arms feature ultra-low friction composite bushings for smooth bind-free movement and optimal weight transfer during launch. The high-strength low alloy steel enables a thinner wall construction and results in an overall lightweight package. Note: GM 2.0 drag race arms are not compatible with factory coil springs and must be used with a coilover system.
