Keep the front suspension tight and precisely located with the Mevotech Supreme control arm and ball joint assembly, CMS20380. This integrated unit combines the control arm with a pre-installed ball joint and drops in at the front left upper position on Dodge B-series and Ram vans, including the 1981-1994 Dodge B150, B250 and B350, the 1995-1998 Dodge B1500, B2500 and B3500, and the 1998-2003 Dodge Ram 1500, 2500 and 3500 Van — see the Buyer's Guide tab for the full application list.
Engineered in-house with application-specific upgrades, this Mevotech Supreme suspension control arm is built for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks.
Worn control arm bushings or a failing ball joint can cause clunks, loose steering and uneven tire wear; if that component is the cause, this assembly replaces it.
