This is our Chevy front Dana 60 specific u-bolt plate. The passenger side plate is laser cut from 1/2" plate steel, the holes are drilled on one side to fit the tapped holes in the axle housing, the opposite side of the passenger side plate is made to fit a standard u-bolt. The drivers side plate is made from 3/8" plate and designed to use 2 standard u-bolts. These can be used on a new build, or make great replacements for your stock u-bolt plates. Sold as a pair, includes one custom u-bolt plate for the passenger side and one standard u-bolt plate for the drivers side. Like all of our products, they are made in the USA from USA steel.
