63-72 Chevy/GMC Truck 1" Narrowed Air Bag Tubular Control Arms. These control arms are 1" narrowed and move the wheelbase 1" forward. They are designed for use with Air Bag suspension. Control arms feature no squeak polyurethane bushings with grease fittings. These control arms are much stronger than stock and all joints are T.I.G welded for strength and durability. They feature high quality ball joints with dust boots and feature bump stops to protect the ball joint at full drop. Control arms are designed to provide 4 degrees additional positive caster for improved handling. These control arms are a direct bolt in upgrade with no modification required. Control arms come with 63-70 upper ball joints so if you are installing on a 71-72 you will need to replace the upper ball joints. Vehicle Appplication:
