Does anyone know if they make a 1/2" block for the rear of the titan ? I have a 1" block back there now and want it lowered a 1/2 " i think since i lowered my front from 2 1/2" to 2"
PRG drop shackles are stout and have adjustment from stock to 1.5 inches of drop I think. You can find lift block cheap cheap on ebay if you don't want to go the shackle route...
Blocks aren't really truck specific as long as it isn't too wide (no wider than 2.5"). I think some ford leaf springs are 3" where everybody else runs 2.5" or similar.
