Adjustable Idler Arm Metric GM 78-88

The Adjustable Idler Arm Metric GM 78-88 from ALLSTAR PERFORMANCE is a vital steering and suspension component specifically designed for select General Motors vehicles from the 1978 to 1988 model years. This idler arm acts as a pivot point in the steering linkage, converting the motion of the pitman arm into precise control of the wheels. It is an essential replacement part for mechanics working on steering geometry or worn steering components.

Engineered with a focus on performance, this adjustable idler arm features a robust steel construction and a design that maintains OEM steering response and alignment tolerances. The adjustable height allows technicians to fine-tune the steering centerline, accommodating suspension modifications or wear in adjacent components. This design helps prevent binding in the steering linkage and reduces stress on the tie rods and pitman arm, enhancing overall durability.

Ideal for restoration projects, suspension upgrades, and fleet maintenance, this component is particularly beneficial for classic and first-generation GM trucks and muscle cars from the late 1970s through mid-1980s. Installation is straightforward, requiring basic hand tools and alignment verification to ensure proper toe-in and caster angles after installation.
