{"product_id":"yp-sj-297x-201","title":"Yukon Chromoly Super Joint, Single, for Dana 30, Dana 44 and GM 8.5\" Front Diffs","description":"Yukon Super Joint for GM 8.5\", Dana 30 \u0026amp; Dana 44. One single joint.\u003cbr\u003e\u003cbr\u003eYukon 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 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":42599524991111,"sku":"YP SJ-297X-201","price":454.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/3925\/1335\/files\/5bc710eb84fc8ad996d6059f1a42653d.jpg?v=1765561260","url":"https:\/\/www.randysworldwide.com\/products\/yp-sj-297x-201","provider":"RANDYS Worldwide","version":"1.0","type":"link"}
