The Yukon Gear Chrome Moly Superjoint is a high-performance replacement u-joint designed for extreme off-road applications. Constructed with a 4340 chromoly cross and caps made from 4140 steel, this joint offers a significant strength upgrade over factory u-joints. Its design isolates wear to the caps rather than the cross, making maintenance more convenient and cost-effective by allowing cap replacement. The larger circumference trunnion enhances durability, and the reservoir at each trunnion end facilitates proper greasing. The Super Joint design eliminates needle bearings, resulting in a more robust component suitable for demanding conditions, though it requires regular regreasing due to the absence of sealed lifetime grease.
This product is compatible with Dana 60, Dana 44, Dana 30, and GM 8.5” differentials, making it suitable for a variety of off-road vehicles and heavy-duty applications. It is intended as a direct replacement or upgrade for existing u-joints in vehicles used in extreme off-road environments, where strength and reliability are critical. Installation involves replacing the factory u-joints with these Super Joints, which are designed for bolt-on fitment. While ideal for off-road use, frequent maintenance is necessary, and it is not recommended for daily-driven vehicles due to the need for regular greasing.
