Cross Shaft

The MOOG K6146 control arm cross shaft is a critical steering and suspension component engineered for classic GM A-Body, B-Body, F-Body, and X-Body vehicles manufactured between 1966 and 1974. As a seasoned mechanic, you know that worn or damaged cross shafts compromise suspension geometry and steering response—this upper cross shaft assembly restores proper alignment and handling characteristics that modern drivers expect from a well-maintained classic car.

This steel construction component measures 19.4 inches in length and weighs 3.35 pounds, engineered to withstand the lateral and torsional loads inherent in suspension articulation. The cross shaft connects the upper control arms on both sides of the vehicle, allowing them to move in unison while maintaining suspension geometry. MOOG includes bushings in this kit, eliminating the need for separate sourcing—the bushings are critical interface components that dampen vibration and allow controlled pivot motion without binding or excess play.

Restoration shops, classic car enthusiasts, and fleet mechanics performing suspension rebuilds on vintage Chevrolet Chevelles, Camaros, Novas, and Pontiacs will find this cross shaft essential when addressing worn suspension systems. Improper cross shaft condition causes tire wear, wandering steering, and decreased cornering stability—issues that become immediately apparent during a test drive. Installation requires disconnection of the upper control arms and removal of the pivot bolts; the bushings provide proper preload and isolation once reassembled. This kit-format design ensures compatibility and simplifies the rebuild process for experienced technicians.
