Yukon Ball Joint Kit for AAM 9.25 Front Differential Both Sides

Replace and upgrade your failing OE ball joints with Yukon’s precision-built units constructed from strong high-tech materials. This kit replaces the upper and lower front ball joints on both sides and includes all the required small parts. Its housing is CNC-machined from forged SAE 1045 carbon alloy steel and the ball stud is made from induction heat-treated, hot-forged 4140 chromoly. These ball joints use military-grade acetal bearings because of their advanced anti-friction properties and dimensional stability. Yukon ball joints feature a two-staged approach with a synthetic Neoprene/CR outer boot and an inner seal/pancake boot that safeguard against contaminants. Includes Grade 8 hardware, castle nuts, c-clips, cotter pins, and zerk fittings. Greaseable, pre-threaded zerk housing. Lifetime warranty against manufacturing defects.
