Yukon Gear YP SJ-297X-203 Chromoly Super Joint Kit for Dana 30/44 GM 8.5"

Yukon Chromoly Super Joint Kit (Pair) for Dana 30, Dana 44, and GM 8.5" Diffs Yukon Super Joints offer an upgrade in strength and durability over factory u-joints and excel in off-road applications. Designed for Dana 60, Dana 44, Dana 30, and GM 8.5” differentials, Yukon Super Joints feature a 4340 chromoly cross and include an installation manual, sticker, grease gun, high-quality anti-seize grease, small parts, joint or joints, and caps.

The caps are made from 4140 steel to isolate the wear to the caps not the cross because it’s a lot more convenient and less expensive to replace the caps. The end of each trunnion is home to a reservoir for the grease. You’ll notice the trunnion is larger in circumference compared to conventional u-joints. This is because the Super Joint eliminates the needle bearings. These joints were never designed for daily drivers so we do not recommend installing them in a vehicle that does not have locking hubs. Fits Dana 30, Dana 44, and GM 8.5" front differentials Two complete joints, eight full circle snap rings, grease and grease gun Not recommended for daily driven use Uses ultra high grade anti-seize for lubrication Design eliminates needle bearings resulting in larger trunnion for added strength
