One Single Joint SJ-297X-201","description":"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 in. 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 \u0026 Axle","offers":[{"title":"Default Title","offer_id":44638179426532,"sku":"YUKYP SJ-297X-201","price":476.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0661\/2566\/0388\/products\/4f4baed8669101bdc24ba0a697d0a1b9_98400f01-141f-4b39-96ee-adf7e0202d8d.jpg?v=1708867072","url":"https:\/\/www.carandtruckparts.com\/products\/yukon-gear-axle-yukon-gear-super-joint-for-gm-8-5in-dana-30-dana-44-one-single-joint-sj-297x-201","provider":"CarAndTruckParts.com","version":"1.0","type":"link"}
