Introducing the Camburg X-Joint, a high-performance ball-joint designed for extreme conditions. Made with heat-treated materials and an improved boot design, it offers increased strength, better greasing, and extended longevity. The fully sealed dual lip seal design prevents contamination from dirt, sand, rain, mud, and snow. With a grease zerk fitting, you can easily grease the joint without removing the boot. Specifically designed for our ball-joint upper arms, the X-Joint provides optimum fit and maximum wheel travel. It corrects suspension geometry, improves handling, and allows for a wider range of alignment adjustment. The tubular construction offers more tire and shock clearance compared to stock arms. CNC bent tubes, MIG welded, and featuring thicker .156" wall round tubing, these arms are built to last. Polyurethane frame pivot bushings with grease-able zerk fittings ensure smooth operation. The Camburg X-Joint comes pre-installed with billet aluminum covers and a matte black powder-coating. All necessary hardware is included for easy installation. Designed for 1-3" of lift, it increases usable wheel travel and corrects camber and caster. Made in the USA in-house, the Camburg X-Joint is the perfect upgrade for 6 lug model trucks.
