Yukon Chromoly Super Joint, Single, for Dana 30, Dana 44 and GM 8.5" Front Diffs

Yukon Chromoly Super Joint, Single, for Dana 30, Dana 44 and GM 8.5" Front Diffs. Yukon Super Joint for GM 8.5", Dana 30 & Dana 44. One single joint.. Yukon Super Joints offer an upgrade in strength over factory u-joints and excel in extreme 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 caps made from 4140 steel to isolate the wear to the caps not the cross because its a lot more convenient and less expensive to replace the caps. The end of each trunnion is home to a reservoir for the grease. Youll notice the trunnion is larger in circumference and therefor considerably stronger than to conventional u-joints. This is because the Super Joint design eliminates the needle bearings. The trade-off is these joints require frequent maintenance as sealed needle bearings contain their grease for a lifetime and Super Joints require regreasing, so we do not recommend installing them in daily driven vehicles.

Fits Dana 30, Dana 44, and GM 8.5" front differentials Includes one complete joints and four full circle snap rings 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
