7. Barnes 4WD


U BOLT, 5/8" X 4" X 10"

Barnes 4WD #ad - When a u-bolt is tightened the u-bolt threads stretch as they mate with the hi-nuts. Our u-bolts bolts have a torque spec of 150 foot pounds and should never be tightened with an impact gun. This stretching is not visible but a U-bolt should never be reused because removing the tall nut will cross thread the U-Bolt.

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. This produces an alloy that is has grade 8 strength but not grade 8 hardness. The mating hi-nuts are hardened as well as the thick washers and are manufactured with sharp cut threads. Our u-bolts are made from a cold drawn 1541 alloy that is stress relieved.

This insures proper tightness of the fastener is maintained. Barnes 4wd u-bolts are anything but standard! this u bolt measures 5/8" X 4" X 10" and are a great fit for a AAM 11. 5, dana 80 or dana 70 HD. The threads on our u-bolts are 5/8"-18 fine threads and are manufactured with a smooth rolled thread. The biggest misconception with u-bolts is that they are all the same; this could not be farther from the truth.
