Today i went out and cranked the T-bars up on my truck. I still have roughly 3/4 before my upper control arms touch the bump stops. I have the stock shocks for now but i ordered new ones just waiting for them to come in. I got 39 1/2 from ground to to of wheel well and 40" in the back. I want to put a block in the back so it doesnt sag. Would you recommend a 1" or 1.5" block. I have 1.5" blocks and still have some room to crank the bars more. I have alittle less them 1/2 of the bolt showing. What would you do?
