Dynatrac Ball Joints feature heat-treated high-strength billet bodies with chromoly stems. The heat-treated, precision-ground stainless steel ball meets military specifications. Unique seals prevent contamination, and the joints have greasable fittings and Teflon-coated wear points to provide a long, durable life. Dynatrac Ball Joints are rebuildable on the vehicle with common hand tools. They resist wear, take abuse and ensure the vehicle’s steering is tight and true for improved safety, handling and driveability while also reducing tire wear.
