    • Well engineered
Size: 1-1/2"
Bought a set to move the rear axle forward some on my custom built 1952 3100 truck. Had to dremel the boss to a smaller diameter to fit into my spring perches but I was expecting some sort of modification. Nothing comes bolt on with custom. Good quality materials and hardware.
