    That's more or less where I'm at now. One full coil off the front and three off the rear. The rear still sits too high, so I ordered a set of Belltech 4" rear coils. I'll try those and see how they are.

    I'm also going to compare the Crown 1/2 springs to these.

    Sweet. I may cut half a coil on the front and the three on the back. I need 20's!

    Well that's what I had before I cut them, so yours should sit pretty close to mine.

    Cool. I don't want mine that low in the front though. So I may just cut half a coil in front. It still seems like you have an inch to inch and a half of rake in the pics. You're running the B/T drop bracket or just the adjustable track bar?

    Yea, start with half a coil and see what you think. You can always cut off more or add a shim.

    And yea, it's still a good inch or two of rake.

    No bracket, and I haven't adjusted the bar yet. It actually just sits about right on its own.

    If you still have issues with the truck not sitting close to level on the left and right side. Loosen all the bolts on the rear upper and lower arms and the pan hard bar. Drive the vehicle slowly in your neighborhood and than on level ground retighten (torque to factory spec) the upper arms, lower arms and pan hard bar with the wheels on the ground. Recheck your measurements and hopefully this helps.

    Yea I made sure not to tighten down the control arms until the suspension was settled. That's not the issue, it's just that the drivers side is a lot heavier on these trucks thanks to the fuel tank.

    For those that don't understand why this needs to be done, it's because factory rubber bushings are preloaded to a set ride height. Rubber bushings twist as the control arms move up and down, and as such they act like a spring. That's why you can't just turn a rubber bushing control arm as it sits. With poly, delrin, or metal, the joint slides rather than twists.
