I recommend contacting PRG Products.So guys and gals I need some help. I am getting ready to redo my rear susp. Currently running a pro comp 3" block. I am wanting to ditch the 3" and go with Deaver c30 approx. 3.5" of lift. Also add 1" block for a total of 4.5" of lift with prg variable height shackles 0, .5, 1.0 of drop. An I still can't find where to buy the bilstein 5160 with the 14mm eyelets that we need for Titan. I am worried the c30 will not give a full 3.5" of lift. Does this all look sound to anyone.
