The Kryptonite KRP0289 Upper Ball Joint is built to take a beating and keep your suspension tight and responsive. Whether you're road tripping or hitting rough terrain, this heavy-duty ball joint offers long-lasting performance where factory joints tend to fail.

• Oversized Heavy-Duty Internals – Built to withstand oversized tires, towing, off-road use, and high-load applications.
• Greaseable By Design – Apply 4–6 pumps during installation, then maintain with approximately 1-2 pumps every 5,000–7,000 miles. Designed to purge contaminants without overfilling the boot.
