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.\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/05d4a95874a9945f545e865a7f24a973.PDF\"\u003eUser 2\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/26b80ba4463a3e963b7e553952fe78cb.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/4593c777d6c1f7f34ea4c91f88148cd5.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e","brand":"Yukon Gear \u0026 Axle","offers":[{"title":"Default Title","offer_id":43969593245920,"sku":"YUKYP SJ-297X-202","price":768.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0610\/0654\/5120\/products\/1a5b56e40fad081a9a4dc16f39925e27.jpg?v=1681446893","url":"https:\/\/797offroad.com\/products\/yukon-gear-chrome-moly-superjoints-replacement-for-dana-30-dana-44-gm-8-5in","provider":"797 Offroad","version":"1.0","type":"link"}
