Dynatrac JK/JKU/WJ Heavy Duty Dana 30/44 Upper & Lower Ball Joint Kit - Set of 4 w/ Knurls

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.

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 accommodate vehicles which previously had competitors' ball joints which may have enlarged or wore the mounting location, and now are switching to Dynatrac.

Fits the following applications:

'07-'18 Jeep Wrangler JK 2 Door
'07-'18 Jeep Wrangler JKU Unlimited 4 Door
'99-'04 Jeep Grand Cherokee WJ
