Description

IMPORTANT NOTICE: This control arms require the use of coil-over shocks and will not work with a factory style spring.

QA1 GM 2.0 Street control arms provide increased positive caster compared to OE arms and are among the lightest available. These arms feature a lower unsprung weight and improved performance without sacrificing durability. Each arm includes a QA1 integrated ball joint design which is stronger than OEM and rebuildable for tunability, providing long-term reliable service. These arms are designed with 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 Street control arms look incredible and use no unsightly additional adapters! Form meets function with these newly designed arms that look and perform great without requiring painstaking restoring like factory stamped steel control arms.

Product Overview

QA1?s Street Control Arms are the perfect upgrade for any vehicle used primarily for cruising and long distances. Configured for QA1 Pro Coil Systems with double shear lower mounting. The combination of high strength tubing and billet aluminum cross shafts make these arms amount to the lightest on the market with improved strength and durability. Robotically welded and high-quality powder coated these street control arms look great. These control arms use polyurethane bushings which will isolate road noise for smoother ride, yet stiff enough for great handling. The high-quality integrated ball joint included with this control arm setup is stronger than the factory ball joint and provides a long-term service. 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. When used independently they will add approximately half of the preceding numbers.
