2. The replacement control arms are built from 1.5x0.120-inchwall DOM tubing rather than inferior mild steel. Designed to work with the factory spindles, the main tubes are longer and angle upward to raise the mounting location of the spindles 5 inches higher, which in turn lowers the front suspension without altering its geometry substantially. The other benefit here is that the arms retain the factorystyle ball joint, so maintenance is cheaper because the ball joints are readily available. The ball-joint mounts are CNC-machined from solid steel stock, and the lower 'bag mount is built from 1/4-inch-thick steel plate. All of the MIG welds looked clean and strong on the arms.
