As promised, here are pics of the sealed setup underneath the hood.
I would imagine this would be similar on a fuel injected engine, just to a throttle body instead of a carb plenum.
Been having some issues getting everything level on the lift.
The original lift was simply a 2.5" front coil spacer, and a 2" rear block. My "just add an inch and a half" plan didn't really work.
The first shot is 3.5" rear blocks, and the front has Rough Country 1.5" leveling springs, plus the 2.5" spacers. The front still sits lower.
The second shot is still 3.5" rear blocks, but the front now has 4" skyjacker coils and a small spacer to make sure the 32" tires clear at full lock. The rear sits just a little lower, but we still have to put in a 6 degree shim to get the pinion angle right, we are hoping that gives the rear just a little boost to level it out.
This is a comparison between stock, 1.5" leveling, and 4" coils. Also the original spacers and the new short spacers.
