2018-2026 Wrangler JL / Gladiator JT Upper Ball Joint (KRP0289)

Description

Wandering steering and clunks over bumps usually point to tired ball joints. Kryptonite upper ball joints for the Wrangler JL and Gladiator JT are built tougher than factory, with heat-treated 4140 chromoly studs and oversized internals that hold up to big tires, towing and hard trail use.

This upper ball joint fits either side, driver or passenger. Each joint presses into the factory Jeep axle with an OE-style fit, and the greaseable design plus E-coat finish keep it working in mud, salt and water for the long haul.

Features

• Heat-treated 4140 chromoly studs resist bending under heavy steering loads
• Oversized heavy-duty internals built for big tires, towing and off-road use
• Greaseable design purges contaminants without overfilling the boot
• E-coat finish for rust and corrosion protection
• Press-in replacement with an OE-style fit
