Ouch. Sorry about the engine. Yes, mine is lifted two ways. The suspension has a 1.75 inch block at the axel. Don't go any higher or you can't use a bag system if you need the extra sag help.. I have the ride rite system and the bag carriers are fully extended. Also the rims at 22" with low profile nitto's lifted it 2 inches. From stock, I'm only 3 inches higher at the tail gate, but it looks taller because the tires and rims. If you raise it 3", you will need to have two piece drive line adjusted, or you will bind the rear end under load. For 3", you need to drop the center carrier bearing 3/4" to adjust the angle to your rear hub. I had a local drive line shop handle it for me for 80 bucks and the truck pulls it perfectly. You will love the new 350. Tow mode and go. The transmission system in tow mode is amazing.
