U-BOLT FLIP KITS: You need to measure your existing rear suspension from the bottom of the axle tube to the top of the leaf pack. Add 2″ to your measurement and that will give you the length of U-Bolt you need. For example, the distance from the bottom of the axle tube to the top of the leaf pack measure 5.5″. Then you add the 2″ required for the U-Bolt flip plate and mounting hardware. This equals 7.5″ in which case you would choose the 7.75″ U-Bolt Flip Kit. Please note all U-Bolts have 3″ of thread.
