Product Description

The MOOG K440019 is a direct-replacement steering pitman arm for 2011-2023 Chevrolet Silverado 2500 HD and 3500 HD, and 2011-2023 GMC Sierra 2500 HD and 3500 HD, in both gas and Duramax diesel configurations. The pitman arm is the critical link between the steering gearbox output shaft and the drag link - it converts the rotational force from turning the steering wheel into the lateral movement that steers the front wheels. When it wears or develops play, symptoms include loose or wandering steering, steering wheel shimmy, and reduced directional control, particularly noticeable under load on these heavy-duty platforms.

MOOG's one-piece engineered steel composite construction eliminates the flex inherent in multi-piece factory designs, delivering a more solid, responsive steering feel suited to the sustained towing and hauling demands these trucks are built for. Precision-machined splines ensure a tight, rattle-free fit on the steering gearbox shaft, and the greaseable design allows service intervals to keep the connection point lubricated over time. For a complete steering linkage refresh, pair this pitman arm with MOOG K400018 (idler arm). A pitman arm puller tool is recommended for proper removal of the old arm during installation.
