The QA1 52626 tubular upper control arms upgrade the front suspension on 1999-2006 Chevrolet Silverado and GMC Sierra 1500 2WD trucks with coil front suspension. The tubular design improves caster for better stability and helps maintain proper alignment through suspension travel, and it is lighter than stock while complementing QA1 coil-overs. The arms are a direct bolt-in replacement for the OEM uppers, work with stock or QA1 drop spindles (part number 9056-120) and come fully assembled with ball joints and bushings installed. They are made in Lakeville, Minnesota with a durable powder coat finish, and they are not compatible with trucks originally equipped with torsion bar front suspension.
