Product Details

Moog RK620800 is engineered as a premium suspension control arm and ball joint assembly for BMW X5 and BMW X6 front suspension service. The forged steel arm is paired with a press-in ball joint, rubber bushings, and included mounting hardware to match the original suspension layout on the front left lower rearward position.

This part cross-references Dorman OE Solutions 521-163 for the same application.

What It Helps Fix

  • Front-end clunking or knocking from worn suspension joints
  • Excessive play in the front left lower rearward control arm
  • Uneven tire wear caused by suspension looseness
  • Steering wander or reduced directional stability
  • Failed rubber bushings or ball joint wear in BMW X5/X6 front suspension

Installation Notes

Compatible with 2007-2013 BMW X5, front left lower rearward, and 2008-2014 BMW X6, front left lower rearward. Verify the vehicle position before installation and confirm the press-in ball joint and threaded stud interface match the original suspension layout. Because this assembly includes bushings and mounting hardware, it is suited for a complete control arm replacement during front suspension repair.
