2018-2026 Wrangler JL / Gladiator JT Upper & Lower Ball Joint Package (KRJ-BJP-18)

Kryptonite ball joints are built to take a beating and keep the front end of your Wrangler JL or Gladiator JT tight and responsive. Heat-treated 4140 chromoly studs and oversized internals stand up to big tires, towing and trail abuse where factory joints tend to wear out.

This package replaces all four factory ball joints, two uppers and two lowers, and fits either side. They are machined for an OE-style press-in fit on factory Jeep axles and finished in a corrosion-resistant E-coat.
