This Mevotech Supreme control arm is engineered in-house with application-specific upgrades and built for high-usage passenger vehicles, SUVs, fleets and working trucks, with Labor Saver designs that speed up the job.

What is it made of?
The arm uses stamped steel construction made to meet or exceed OE specifications, plus a protective surface treatment that helps resist corrosion.
