Common Uses

  • Replacing a worn or damaged front lower control arm on a Dodge Ram 1500
  • Replacing a front lower control arm on a Dodge Ram 2500 with Dana 44 axle
  • Addressing looseness, clunking, or uneven front suspension movement
  • Restoring front suspension alignment and control arm geometry

Installation Notes

Install the RK640398 in the front lower position only. Mounting hardware is not included, and the ball joint is not included, so verify the existing service parts before installation. Because this control arm is not adjustable, confirm vehicle application and suspension configuration before beginning the repair. Professional alignment is recommended after front suspension component replacement on Dodge Ram 1500 and Dodge Ram 2500 trucks.
