Complete set of patented, made-in-the-USA, rebuildable, Dynatrac HD Balljoints™ for 2007-2018 Jeep Wrangler JK and 1999-2004 Jeep Grand Cherokee (WJ). Fits stock front axle or Dynatrac ProRock 44™ for Jeep JK applications. Dynatrac HD BallJoints are the strongest, most durable and highest quality available anywhere, featuring 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 ball joints have greasable fittings and Teflon-coated wear points to provide a long, durable life. Dynatrac HD BallJoints are rebuildable -- they can be rebuilt on the vehicle with common hand tools.
Please note that installing knurled ball joint bodies permanently alters and creates unrecoverable wear in the end forging and knuckle bores. Knurled bodies should only be used only as a last resort. We sell knurled versions to accomodaete vehicles which previously had competitors' ball joints which may have enlarged or wore the mounting location, and now are switching to Dynatrac.
