Product Description
The MOOG K6654 Pitman Arm is engineered to restore tight steering response and proper steering linkage geometry in heavy-duty GM trucks. Designed with a 3-groove / 33-spline sector shaft interface, this premium replacement pitman arm connects the steering gearbox to the center link, translating steering wheel input directly to wheel movement. When the factory pitman arm wears out, steering can become loose, vague, or unstable — replacing it with a high-quality MOOG component helps restore factory-level steering precision.
Built from high-strength engineered steel, the MOOG K6654 features a greaseable powdered-metal gusher bearing that allows lubricant to penetrate critical wear surfaces. This design helps reduce friction, improve durability, and extend service life in demanding truck applications such as towing, hauling, and heavy diesel use.

FAQ
What does a pitman arm do in the steering system?The pitman arm connects the steering gearbox to the center link or drag link, converting steering box rotation into side-to-side movement that turns the wheels.
What are signs of a worn pitman arm?
Common symptoms include loose steering, excessive steering play, clunking noises while turning, wandering on the highway, and uneven tire wear.
Is the MOOG K6654 greaseable?
Yes. This pitman arm uses a gusher bearing design that allows grease to flow through the internal bearing surfaces for improved lubrication and longevity.
Will this fit Duramax trucks?
Yes. The MOOG K6654 fits many 2001-2010 Silverado and Sierra 2500HD/3500 trucks including Duramax diesel models that use the 33-spline steering gearbox.
Should I replace the idler arm at the same time?
It is often recommended. Pitman arms and idler arms wear at similar rates and replacing both can restore steering geometry and improve steering stability.
