I would think the diesel would be a little bit heavier than the gasser. I haven't seen under the hood of a 6.2 but I also haven't seen much under the hood of a 6.7 because thats all thats there is 6.7, sum bitch is HUGE!!

technically, must of the lifts for the Super Duty are for the 6.7L. Most of the manufactures state that the lift will not fit the gasser 6.2L.
The lift companies never mention "why" the lift won't fit the gasser, but its because the front drive-shaft will come into contact the the catalytic converter if a lift any bigger than 2.5" is put on a gasser. I found this out by picking up the phone and calling ReadyLift. So that's the reason why I had a custom front drive-shaft made for my truck. It is 2" in diameter and solid...so it likely has more strength than the factory shaft. The reduced diameter allows it to fit along side the converter, without bumping into it.

I just cant understand it fellas,Took 2" stock block out of rear(measured almost 2") and replaced with 6" block, and what to I get for lift=3". LOL 
Talked to friends ect.... and they have no idea either,sum suggested that with the lift in front shifted the whole suspension and kinda putting a more or a bind on the leafs in rear causing it to not lift the 4+" that it should have? Driving me nuts.Gota call readylift tommorow and see if they sell the 3.5 spacer sperately instead of whole kit, and or look for smaller springs but far as I know all thats out there are 4" or bigger springs.
