QA1's GM 2.0 Control Arms provide increased positive caster compared to OE arms, are among the lightest arms available featuring lower unsprung weight and improved performance without sacrificing durability. They include QA1's integrated ball joint design: stronger than OEM and rebuildable for tunability, providing long-term reliable service. These arms feature billet cross shafts for reduced weight and durability for the long haul. Double-sheer lower mounts are coil-over ready for a clean installation. QA1 GM 2.0 Control Arms look incredible and use no unsightly additional adaptors! Form meets function - these newly designed arms look and perform great and don't require painstaking restoring like factory stamped steel control arms.High strength, low alloy steel enables optimized thinner wall construction and results in overall lighter weight. QA1's integrated low-maintenance ball joints feature integrated ball joint dust boots, are stronger than competing ball joints, give long-term service and are rebuildable. QA1 GM 2.0 Control Arms will work with either OE or drop spindles. Increased positive caster design improves straight line stability. Mounts in OE location with no cutting, fabricating, or welding required. Accommodates either factory or aftermarket disc brakes.Q2.0 Pro Touring Series arms feature a 1" longer upper ball joint stud for increased negative camber gain to keep the tire contact patch optimal for superior grip while cornering. They have low friction ball joints that are adjustable for bind-free movement and can be rebuilt to use different ball stud lengths. The composite bushings are ultra-low friction and eliminate flex, providing bind-free movement and superior performance.All of these arms are designed to add 3-4 degrees of caster and 0.5 to 1 degree of negative camber when used together (i.e. upper & lower). When used independently they will add approximately half of the preceding numbers.All parts sold in pairs and including mounting hardware. Made in the USA.
