My truck is a 4x4 king ranch. The truck has 60,000 miles. The truck sits a 1/2" lower in the back, the HBS steel kit in 2.5 does raise the front slightly higher why I don't know. I am adding a 1.5" rear block kit tomorrow and will see how that is. Tire pressure is 34psi with 12 degree temps. I need to raise the rear any ways because if go through anything that flexes the suspension the tires in the rear will rub my inner bed side.
