Spicer Front Steering Knuckle Kingpin Master Rebuild Kit for Chevy, GM & Ford (Dana 60, Single Side)

Eliminate violent front-end death wobble, correct erratic steering wander, and completely rebuild your heavy-duty steering knuckle pivots with this genuine Spicer Kingpin Master Rebuild Kit. Specifically engineered to overhaul iconic Kingpin Dana 60 solid front axles, this comprehensive single-side package replaces all worn-out upper and lower steering knuckle components.

On classic 1-ton 4x4 platforms, the steering knuckles rotate on a heavy-duty mechanical interface consisting of a threaded upper steel kingpin and a lower tapered roller bearing. Over high mileage, intensive commercial fleet use, or rugged off-road trail abuse, the upper nylon cone bushings distort or split, the massive tension springs fatigue, and the lower bearings fall victim to moisture contamination and pitting. When these components develop excess play, it introduces dangerous lateral slop into the steering knuckle—resulting in severe front-end tracking instability, accelerated tire wear, and an unresponsive steering wheel feel.

This original equipment manufacturer (OEM) master service package supplies everything needed to properly refresh one complete front steering knuckle station. Sourcing genuine Spicer components guarantees exact original equipment dimensional specifications, correct steel tempering for high-torque loads, and high-density polymer formulas engineered to handle extreme vertical chassis weight without premature failure.
