Description

The Yukon Ball Joint Kit for AAM 9.25” Front Differential is a direct replacement part designed to restore proper suspension function. This kit is specifically for one side of the vehicle and includes both the upper and lower ball joints, as well as all necessary small parts for installation. Constructed with a CNC-machined forged SAE 1045 carbon alloy steel housing, this kit promotes longer joint life by providing a robust foundation. The ball stud itself is made from hot-forged, induction heat-treated 4140 chromoly, known for its exceptional durability and resistance to wear. Furthermore, the kit incorporates extrusion rolled threads, which are inherently stronger than traditional cut-thread construction, ensuring a more reliable and secure fit. This Yukon Gear and Axle ball joint kit comes with a lifetime warranty against manufacturing defects, reflecting the manufacturer's confidence in its quality and construction. It is designed to fit AAM 9.25” front differentials.
