Ball Joints

OEM Stock Replacement Factory Ball Joints

Ball joints are an integral part of the front suspension and steering system. Worn parts will result in sloppy steering, noise and generally unsafe operation. West Coast Differentials carries a wide selection of genuine factory-replacement components from Dana Spicer and AAM. We have sets available for Jeep, Dodge, Chrysler and Ford vehicles. Tighten up that sloppy front-end! Most of our kits come in pairs and contain the upper and lower joint, and AAM units are offered individually as upper or lower. Most factory-replacement parts are available and in stock for immediate shipment or will-call pickup.

Synergy Ball Joints

Synergy Manufacturing has developed a high-performance alternative to factory replacement parts. Synergy’s advanced design results in an extremely durable and wear resistant joint, backed by a 12 Month Unlimited-Warranty. Replace the factory parts that are prone to premature failure on lifted vehicles with large off-road tires. Call our sales department for updated applications and availability.
