Howe Extreme Duty Precision Low-Friction K772 Upper Ball Joints
Howe XD Extreme Duty Precision Ball Joints are engineered for racers who demand maximum strength, precision, and durability from their suspension and steering components. By combining the accuracy of a spherical bearing with the misalignment capability of a traditional ball joint, these ball joints deliver smoother suspension travel, reduced steering effort, and consistent, confidence-inspiring performance.
 
Built with a mil-spec alloy housing that is 300% stronger than OEM, XD ball joints are designed to survive the extreme loads and abuse seen in Modifieds, Late Models, and other high-stress short track applications. Process-coated, low-friction steel ball studs reduce friction and wear, resulting in more responsive steering and improved suspension compliance.
 
Fully rebuildable and adjustable, Howe XD ball joints allow teams to service and fine-tune their suspension for long-term reliability and peak performance.
