Sierra 2500HD / 3500 2001-2010 GMC - Upper & Lower Ball Joint Kit (for aftermarket control arms) by Kryptonite

The Kryptonite 0110BJPACK Upper and Lower Ball Joint Set are built for heavy-duty performance, offering unmatched durability and strength for lifted GMC Sierra 2500HDs and 3500s with large off-road tires. These precision-engineered components are designed to replace factory ball joints prone to premature wear and provide superior longevity and reliability in the most demanding conditions.

Each ball joint features a fully greaseable metal-on-metal design, ensuring smooth operation and extended service life. The machined bearing housing is crafted from a high-strength blend of sintered graphite, bronze, and 1045 steel, creating a tough and resilient bearing surface. The ball joint stud is made from 4140 steel with an induction heat-treated bearing surface, delivering maximum durability and effortless movement. A tear and wear-resistant silicone polyurethane boot provides additional protection, maintaining performance over time. Coated with a durable E-Coat finish, these ball joints resist corrosion and maintain integrity even in harsh environments. Pre-greased with premium Chevron Ultra EP2 Grease, they arrive ready for installation, requiring service every 7,000 to 10,000 miles with minimal grease application.

Backed by the Kryptonite No Fine Print Lifetime Warranty, these ball joints are built to withstand anything you throw at them. Whether you race, jump, off-road, or push your vehicle to the extreme, Kryptonite guarantees their performance. If you break it, they’ll replace it.
