UMI's F-150 front coilover bracket kit is designed to give the truck enthusiast a great mounting option for traditional 2-1/2" dia coilover shock and spring systems. UMI's full kits utilize Viking coilovers but 656061 bracket kit can also accomodate most other brands. Note: springs and shocks not included. Set truck at desired ride height and measure to determine proper shock length. Choose spring based on shock ride height.
