Spicer Front Axle Lower King Pin for 1975-1993 Dodge W250, W350, Chevy & Ford (Kingpin Dana 60, Single Component)

Eliminate harsh front-end play, stabilize steering tracking, and restore uncompromised structural integrity to your classic heavy-duty truck with this genuine Spicer Front Axle Lower King Pin. Specifically engineered as a high-durability original equipment replacement for 1975–1993 Dodge W250 and W350 4x4 trucks, as well as vintage 1-ton Chevy/GMC and Ford kingpin platforms, this single tapered spindle pin provides the essential structural pivot point required to rebuild a loose, pitted, or neglected steering knuckle assembly.

On classic mono-beam Dana 60 solid front axles, the steering knuckles do not use modern ball joints. Instead, they rely on an ultra-rugged, industrial-grade kingpin configuration. The lower section of this system utilizes a precision-machined, hardened steel kingpin that mounts tightly onto the knuckle shell and seats down into a heavy-duty tapered roller bearing within the inner C-axle ear. Over decades of heavy commercial hauling, snowplowing, or trail riding with massive off-road tires, this lower pin can develop deep pitting, rust scars, or flat spots due to moisture intrusion or lack of grease. A worn lower kingpin introduces structural slack into the steering knuckle pivot axis, leading to severe tire cupping, unsafe steering wheel shimmy, low-speed clunking, and a total loss of front-end alignment stability.

This original equipment manufacturer (OEM) replacement component is forged by the industry’s benchmark drivetrain supplier from premium-grade carbon-alloy steel, induction-hardened to exact case depths, and ground to microscopic factory tolerances. Choosing a genuine Spicer kingpin guarantees uncompromised metallurgical density and a flawless fit into your factory steering knuckle, avoiding the rapid wear or loose housing tolerances common with cheap aftermarket alternatives.
