So I'm planning on cranking up my T-bars and throwing some blocks in the rear, just a 2" crank and a 2" block; and my questions are;
Will I need longer shocks or will they adjust to the raised ride height? And how many thread will need to be backed out on the Torsion key bolts to achieve 2" of lift? And will that be too much or just right?
They won't adjust, although they may not top out. Think of it like this, say your shock now has 10" of travel, and sits right at 5, then it has 5 up, and five down (these aren't the number's, but you get the idea). Now you do a 2" crank. Now you have 3" up, and 7" down. So now, when you drive into a pothole say, your shock tops out BAM! This is why donk's have such harsh rides. It's a problem on my Trailblazer because no one makes a longer strut for it. So you won't die or anything, but you may want to plan on upgrading shocks eventually.
Whenever I crank them, I just measure from the center of my hub to the center of the fender, note the number's, crank away until I get where I want to be, then make the number's match.
