Mastodon Tubular Control Arm Kit GM 65-70 Full Size Cars

Performance tubular upper and lower control arms for 1965–1970 GM full-size cars (Impala, Caprice, Biscayne, Bel Air, B-body). Built from large-diameter DOM tubing with greaseable bushings, these arms eliminate the camber problems that show up the moment a drop spindle or lowered coil goes in, and give you the caster correction needed for modern tires.

The unique geometric shape provides a distinctive caster-coupled camber curve that reduces factory bump steer and the vague straight-line feel of a 60-year-old chassis. Built-in +5° caster sharpens steering response and improves high-speed stability.
