Sierra 2500HD / 3500HD 2011-2026 GMC - Upper & Lower Ball Joint Kit (for aftermarket control arms) by Kryptonite

Designed for heavy-duty performance, the Kryptonite 119BJPACK-2 Upper and Lower Ball Joint Package for the GMC Sierra 2500HD or 3500HD is built to withstand the toughest conditions while delivering smooth, long-lasting operation. Engineered to outperform factory ball joints, this package is ideal for lifted vehicles with large off-road tires, offering superior strength and durability.

Each ball joint features a fully greaseable metal-on-metal design with a machined bearing housing made from sintered graphite, bronze, and 1045 steel, ensuring a strong and smooth bearing surface. The ball joint stud, crafted from 4140 steel with an induction heat-treated bearing surface, provides maximum longevity and reliability. A tear- and wear-resistant silicone polyurethane boot further enhances durability, keeping dirt and debris out for extended performance. All joints come pre-greased with premium Chevron Ultra EP2 Grease and are ready for installation. To maintain peak performance, servicing is recommended every 7,000-10,000 miles, applying only a small amount of grease per joint. A durable E-Coat finish protects against corrosion, ensuring these ball joints maintain their integrity in the harshest environments.

Kryptonite No Fine Print Lifetime Warranty guarantees coverage against manufacturer defects, premature wear, or breakage. Whether it's racing, off-roading, or heavy-duty work, if a ball joint breaks, Kryptonite will replace it. To qualify for warranty coverage, products must be purchased from an authorized dealer and registered within 90 days of purchase.
