Idler arms are used on vehicles with “box steering” systems, usually trucks and rear wheel drive passenger vehicles. The idler arm assists the Pitman arm by supporting other steering linkage components as it travels in the direction controlled by the steering gear.


The bracket side of the idler arm is mounted to the frame side of your vehicle on one end and supports a ball joint on the other. Typically, an idler arm is positioned on the opposite side of the center link from the Pitman arm, allowing it to hold the center link at the correct height.


Depending on the vehicle application, idler arms may be considered:

  • Arm type

    Arm type idler arms consist of an arm with mounting points on one end that attach to the frame of the vehicle, while the other end of the arm is connected to the main body through a bearing.

  • Bracket type

    Bracket type idler arms contain the pivot assembly within a forged housing, which bolts directly to the frame of the vehicle with the bearing contained inside the assembly.


What makes our idler arms so great? Mevotech gives technicians the edge, by innovating every chassis component. Our engineers focus on making our parts faster and easier to install, while ensuring they are built to provide a longer service life. Employing punishing durability testing, we validate every new design to ensure you get performance you can trust.


For maximum service life and durability we engineer X-Factor upgrades to keep your vehicle performing longer.

  • Greaseable Ball Joints
    Greaseable Ball Joints

    Ball Joint is serviceable allowing the user to continue to grease the ball joint improving the service life of the ball joint.

  • Sintered Metal Bearings
    Sintered Metal Bearings

    Bearings made of a durable sintered powder metal that leads to a longer lasting part.

  • Self-Sealing Grease Relief
    Self-Sealing Grease Relief

    Grease relief that acts like a one-way valve allowing excess grease to flow out of the boot while preventing contaminants entering the boot.

  • Anti-Corrosion Coatings
    Anti-Corrosion Coatings

    Corrosion resistant coatings that prevent the formation of rust for a longer part service life.
