Mastodon Tubular Control Arm Kit GM 73-87 C10 GMC Truck

Performance tubular upper and lower control arm kit for 1973–1987 Chevrolet C10 and GMC C15 squarebody trucks. A bolt-in upgrade engineered for the platform that ditches the deflection of factory stamped arms and lets you run drop spindles or air-bag suspension without geometry headaches.

Constructed from 1.250" 1020 DOM tubing with .250"-thick 1018 steel ball-joint plates for a no-deflection design. Built-in caster correction (+2°) keeps the truck tracking straight on the highway.
