Detailed Description

The Dorman Premium XL line focuses on extended-life steering components, and PA6654XL follows that approach with durable steel construction, a black e-coated finish, and internal wear surfaces designed for consistent movement.

This steering pitman arm is built with a 32 mm steering shaft diameter, 14 mm center link end attachment diameter, and standard ride height specification. It is a practical replacement for worn steering linkage parts on heavy-duty and full-size applications where steering feel and joint durability matter.

What It Is Used For

• Restoring steering linkage movement when the original pitman arm is worn.
• Reducing looseness or play in the steering system.
• Addressing steering response issues caused by worn ball or bearing surfaces.
• Replacing a corroded or damaged steering pitman arm.
• Supporting proper steering transfer in heavy-duty truck and van applications.

Verify spline count, shaft diameter, and center link attachment details before installation. This part fits 2007-2010 Chevrolet Silverado 2500 HD, 2009-2020 GMC Savana 3500, and other listed applications; some fitments note a 3-groove pitman arm requirement. Use the included castle nut and cotter pin during installation, and confirm steering alignment after replacement.
