~ Mounts vertically near differential ~ Adjustable length will tilt rear subframe to change camber setting. ~ Only one arm is required per car ~ Steel Turnbuckle with Copper Metallic Paint ~ Steel bearing side spacers with Gold Finish ~ CrMo Teflon lined rod ends ** If using with solid subframe and diff mounts, you must loosen subframe and diff before adjusting arm length to allow subframe to tilt. Then re-tighten subframe and diff after camber is set. Shorten arm to acheive less negative camber. Shorten this arm to get closer to zero camber on lowered cars.
