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 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 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.","brand":"Yukon Gear and Axle","offers":[{"title":"Default Title","offer_id":47161259131078,"sku":"YP SJ-733X-731","price":798.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0761\/9680\/6854\/files\/5bc710eb84fc8ad996d6059f1a42653d_196ef216-0110-44f6-a1a1-e89b8ac83250.jpg?v=1788922997","url":"https:\/\/fullthrottlewrenches.com\/products\/yp-sj-733x-731","provider":"Full Throttle Wrenches","version":"1.0","type":"link"}
