Complete set of patented, made-in-the-USA, rebuildable, Dynatrac HD Balljointsâ„¢ for 2007-2018 Jeep Wrangler JK and 1999-2004 Jeep Grand Cherokee (WJ). Fits stock front axle or Dynatrac ProRock 44â„¢ 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.

Note:
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.
