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":42594918432903,"sku":"YP SJ-297X-202","price":768.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/3925\/1335\/files\/646f9f83dbd5a0acfdd81e7e9c31612a_9c6ba534-69de-45fe-994b-33f5ee055c0e.jpg?v=1765561185","url":"https:\/\/www.randysworldwide.com\/products\/yp-sj-297x-202","provider":"RANDYS Worldwide","version":"1.0","type":"link"}
