ACDelco Professional Idler Arms come with advanced features not all competitors have. The right technology does make a difference.

  • Cold-formed, heat-treated and precision-machined T-stud, where applicable, allows for reduced friction and eliminates end play for optimum performance
  • Patented, low-friction bearing set, where applicable, provides constant ease of rotation and maintains zero side-to-side motion
  • Heavy-duty, conical coil spring, where applicable, provides better shock absorption and maintains uniform torque
  • Application-specific design bearings are larger and taller, which eliminates end play and side-to-side movement - for optimum performance
  • Precision-machined housing allows for lighter, more consistent tolerances for excellent performance
  • Brackets and arms are hot-forged for added strength and to help support the unsprung vehicle weight
  • Integrated Silent-bloc bushings provides for excellent performance
  • Permanently attached polyurethane dust boots, where applicable, resist cracking, splitting and dry rotting, thereby eliminating contamination - for superior performance and long life
  • Zinc-coated, heat-treated end caps, where applicable, extend service life and provide a rigid preload contact surface for superior vehicle handling
