Stop in for a cup of coffee

the only reason I bought a kit for my current truck is that it included all the needed brackets and bolts.. the blocks are 1.25" polymer... I personally think the polyurethane in an area that doesn't (and shouldn't) move is junk science
My lift blocks are some kind of plastic(polymer) stuff, but the 'biscuits' are polyurethane instead of the factory rubber pieces.
