I ordered a 4.5" kit. However, it is nearly 3.25" taller than my truck was with a 2.5" kit and a TEI spacer. So from original specs the truck is almost 6.3" taller than stock from the center of the wheel hub to the fender lip.
The kit came with a 5" rear block which is clearly not enough so now I've got to dial in the rear end while I wait for these coils to settle.
