Rockwell U-Bolt Plates
These are designed with the standard 2.5" GM leaf spring in mind but will work great with any spring that is 2 3/8" to 2 5/8" in width. These are for the Rockwell Axle 3 5/8" Square (Standard 2 1/2 Ton). All of our U bolt plates have 3 spring pin location options. They are .375" HR P&O Steel plate and can work with .5625" (9/16) to .625" (5/8) U bolts, we recomend 5/8", why use a lighter piece of steel when you don't have too?
