Spicer Front Upper Kingpin Nylon Cone Bushing Set for Dana 60 Axles (Pack of 2)

Eliminate violent front-end death wobble, correct erratic steering wander, and restore tight rotational clearance to your heavy-duty steering knuckles with this genuine Spicer Front Kingpin Nylon Cone Bushing Set. Specifically engineered as a direct replacement for legendary Kingpin Dana 60 solid front axles, this matched pair of high-compression bushings is essential for overhauling loose steering pivots.

On classic 1-ton 4x4 platforms, the upper steering knuckle relies on a heavy-duty tapered nylon bushing seated directly over the steel kingpin. This bushing acts as the primary friction and load-bearing interface during steering articulation. Over high mileage, intensive commercial towing, or rugged off-road trail abuse, these nylon components naturally wear down, compress, or split. When they develop excessive play, it introduces dangerous lateral slop into the steering knuckle—resulting in an unstable "death wobble" at highway speeds, rapid front tire wear, and a loose or unresponsive steering wheel feel.

This original equipment manufacturer (OEM) bundle provides a complete refresh for both the driver and passenger sides, or a full replacement for a single dual-bushing layout. Molded from high-density, self-lubricating nylon polymer formulas, choosing genuine Spicer components guarantees exact original factory dimensions and matching material compression ratings required to handle extreme vertical loads and sudden trail impacts without binding or premature cracking.
