The pitman arm is one of the key links between your steering box and center link. When it starts wearing out, steering can feel loose, wander more than it should, and put added stress on the rest of the steering system.
The PSC PA803 XD Pitman Arm is designed for Chevrolet and GMC 2500HD and 3500HD trucks that see real work. Whether the truck spends its life towing, hauling, traveling rough roads, or carrying larger tires, this heavy-duty pitman arm is built to provide a solid connection and long service life.
Featuring a forged steel housing, heat-treated chromoly stud, and greaseable design, the PA803 is built to handle the loads that heavy-duty GM steering systems encounter every day.
When you're freshening up the front end, replacing a worn steering component, or installing other steering upgrades, this is one of those parts worth doing right the first time.

Tech Info
Heads‑up for installers
- A pitman arm puller is typically required for removal.
- Inspect the idler arm, center link, tie rod ends, and steering gear while you're in there.
- Grease the joint before putting the truck back on the road.
- Always torque hardware to factory specifications.
- A worn pitman arm usually isn't the only worn steering component, so it's a good time to inspect the entire linkage.
