Most certainly will take measurements. I plan to lift and drive with stock tires for a couple of weeks to let things settle and decide how it rides compared to stock. Then add my tires after that. It won't be easy to hold off on the tires, but in the name of science I will make that sacrifice. LOL
Personally I want a touch of rake. Anytime people say their truck is dead level (when taking measurements) the overall look to me is not right. I think it looks nose high. I'm really hoping by measurements, my rear will be 1 inch higher than the front. Giving it a level look with out looking like it has as saggy bottom.
I have read the Rough Country 3.5" rear lift spacer only lifts around 1" of rear height. You have to call them and ask for a larger spacer. Since I was piece mealing this kit together, I went the Supreme Suspension 2" rear spacer. which is just a touch higher than the Readylift 3.5" rear spacer. I posted pics on that already in another thread.
