MI’s heavy duty boxed control arms are built from oversized North American boxed steel tubing, thick wall bushing holders and the highest quality polyurethane bushings. This heavy duty set up is designed to replace the factory set-up minimizing wheel hop while helping track consistency. Aftermarket control arms eliminate flex and bushing deflection found in the factory lower control arms but replacing flexible steel with boxed construction and rubber bushings with greaseable polyurethane. This heavy duty version is built using 1-1/4” x 2” rectangular tubing featuring a 1/8” wall thickness, oversized bushing holders, MIG welded fabrication and finished with a gloss powdercoat.
