{"product_id":"u-bolt-5-8-x-4-1-4-x-10","title":"U Bolt, 5\/8 X 4 1\/4 X 10","description":"\u003cp\u003eBarnes 4wd u-bolts are anything but standard! This u bolt measures 5\/8\" X 4 1\/4\" X 10\".  The biggest misconception with U-bolts is that they are all the same; this could not be farther from the truth. We feel that U-Bolts are the most important component of a leaf spring suspension and this is why we are so meticulous about the specifications of our U-bolts. Our U-bolts are made from a cold drawn 1541 alloy that is stress relieved. This produces an alloy that has grade 8 strength but not grade 8 hardness. The threads on our U-bolts are 5\/8\"-18 fine threads and are manufactured with a smooth rolled thread. The mating Hi-Nuts are hardened as well as the thick washers and are manufactured with sharp cut threads. When a U-Bolt is tightened the U-Bolt threads stretch as they mate with the Hi-Nuts. This insures proper tightness of the fastener is maintained. This stretching is not visible but a U-bolt should never be reused because removing the tall nut will cross thread the U-Bolt. Our U-bolts bolts have a torque spec of 150 foot pounds and should never be tightened with an impact gun.\u003c\/p\u003e","brand":"Barnes 4WD","offers":[{"title":"Default Title","offer_id":50457114116382,"sku":"B4WUR425","price":15.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/7171\/1262\/files\/625x3375x10-U-Bolt_6239176b-8e34-459e-a4bc-4a7596f667d7.jpg?v=1766695307","url":"https:\/\/platinumhpsolutions.com\/products\/u-bolt-5-8-x-4-1-4-x-10","provider":"Platinum High Performance Solutions, LLC.","version":"1.0","type":"link"}
