Yukon Gear YP SJ-733X-731 Chrome Moly Superjoint Replacement For Dana 60
Yukon Gear Super Joints deliver added strength over factory u-joints for extreme off-road use in Dana 60 Dana 44 Dana 30 and GM 8.5” differentials on Chevy K30 V30 Ford F-250 F-350 Dodge Ram 3500 W250 W350 and GMC K3500 trucks. Built with a 4340 chromoly cross and 4140 steel caps the design directs wear to replaceable caps instead of the cross for easier maintenance. Larger trunnions without needle bearings provide greater durability though regular greasing is required making them ideal for off-road builds not daily drivers.
Key Features
- 4340 Chromoly Cross – High-strength core resists failure under heavy torque and abuse
- 4140 Steel Caps – Isolate wear to caps for cost-effective replacements versus full joint swap
- Grease Reservoir Trunnions – Built-in grease pockets on each end for reliable lubrication
- Larger Diameter Trunnions – Increased circumference boosts strength over standard u-joints
- No Needle Bearings – Eliminates bearing failure points for smoother operation in rough terrain
- Extreme Off-Road Design – Engineered for Dana 60 and compatible diffs in heavy-duty trucks
