Product Description
Restore steering strength and eliminate front-end play with the PSC PA807 Idler Arm for 1999.5–2006 GM 2500HD and 3500HD 4WD trucks. Designed by PSC Steering Components to handle the increased loads created by larger tires, lifted suspensions, and heavy-duty diesel applications, the PA807 is a premium replacement idler arm built to outperform factory steering components. Unlike factory idler arms that commonly wear out under heavy loads, the PSC PA807 is engineered with reinforced internal components and high-strength construction to provide improved durability, tighter steering response, and longer service life. This makes it an ideal upgrade for Duramax-powered Silverado and Sierra trucks used for towing, off-road work, and heavy-duty daily driving. PSC steering components are trusted by off-road racers, diesel performance builders, and heavy-duty truck owners who demand stronger steering systems capable of handling extreme loads. If your GM HD truck suffers from steering wander, loose steering feel, or premature front-end component wear, the PSC PA807 idler arm provides the strength and reliability your steering system needs.

Frequently Asked Questions
What does the idler arm do on GM HD trucks?
The idler arm supports the steering center link on the passenger side of the vehicle. It keeps the steering linkage properly aligned while allowing it to pivot as the wheels turn.
Why upgrade to the PSC PA807 idler arm?
PSC builds this idler arm with stronger internal components than stock units, improving durability and reducing steering play in heavy-duty applications like towing or off-road driving.
Will this fix loose steering on my Duramax truck?
A worn idler arm is one of the most common causes of loose or wandering steering on GM HD trucks. Replacing it with the PSC PA807 can significantly tighten steering response.
Does this fit 2WD trucks?
No. The PSC PA807 is designed specifically for 4WD GM 2500HD and 3500HD trucks from 1999.5 through 2006.
Is installation difficult?
Installation is similar to replacing a factory idler arm and typically requires basic hand tools along with a puller for removing steering linkage components.
