Many trucks come from the factory with U-Bolts down configuration, such as most GMC's, Chevrolet's, 2nd Gen Dodge's, and 2011+ Ford Super Dutys. On many trucks, if the U-Bolts are still in good shape, they can be reused when installing this mount.

This very high quality axle bar mount comes beautifully powder coated satin black. The powder coating is done in one of the best shops in the northwest. Each part gets sand blasted and dipped in phosphate on a production automated coating system to be sure it is the best coating we can possibly produce. Every part is hand inspected before and after powder coating to be sure the part meets out high quality standards. After the part passes inspection it is individually wrapped in high quality packaging and boxed in 275lb double wall box to be sure it arrives unmarred.
