Reference Information

99-06 GM Extreme Idler Arm

Performance Steering Components offers XD idler arms for a variety of applications, including many Chevrolet, GMC, and Hummer vehicles from 1999 and up. Their cold-headed stud with reverse pin prevents center link roll. Induction through hardened and annealed SAE 4140 stud provides extreme wear resistance. Idler arms act as a pivot point, supporting one end of the center link, which is connected to the Pitman arm on the opposite side. The idler arm is typically mounted to the vehicle's frame and helps maintain the proper height and alignment of the steering linkage, ensuring smooth and accurate steering.
