Mastodon Tubular Control Arm Kit GM 63-70 C10 GMC Truck

Heavy-duty tubular upper and lower control arm kit for 1963–1970 Chevrolet C10 and GMC C15 trucks. Direct bolt-in replacement for the factory stamped arms — adds front-end strength, sharpens steering response, and corrects the camber/ball-joint angle problems that show up the moment a drop spindle or lowered coil goes in.

Built from large-diameter DOM tubing with greaseable bushings and stock-style ball joints. Includes an extra 2 degrees of caster for straight-line stability and the road feel a worn-out factory front end can't deliver.
