Key word here is diesel mechaninc. Most diesel 4x4s have a solid front axle and do not have all sorts of crazy suspension geometry like an IFS does. 2.5 is about the highest you can go and still retain a safe geometry and a smooth ride. Any greater than that you will ride a lot stiffer and go through ball joints rather quickly.

 

Either way the truck isn't gonna be hurt with half an Inch more

 

Believe it or not, it does hurt components in a relatively short period of time. Mine is about 2.5 (Ranch0 Quicklift) and my upper ball joints are wearing out prematurely.

 

I have an 01 Scab. I'm thinking about 2.5" level from rough country. Will this hurt anything??? It comes with new shocks, keys, and blocks for the rear I think.

 

I had one on my old truck(01 crew cab) just like that I loved it and I cleared 35s easy

 

Any increased pressure that caused problems?

 

The only real problem that I had is I cranked the t bars a little and the upper control arm would bottom out and that was a easy fix just adjusted it down a half turn on each side it ride great but other than that no problem at all

 

i have an 05 screw 2wd and I have toyed around with this set up. I added factory 4x4 blocks in the back and did a 3" spacer in the front. It put a lot of angle on the front end and my steering wheel was never straight. It also put a lot of stress on the upper control arms to the point where they looked excessively stretched out. I took the spacer out and put bilstein adjustable in the front and 4x4 shocks on the back. I set it to the highest setting and there is still a slight rake to it. I am thinking about putting a add a leaf in the back to see where it puts the truck. Steering wheel is straight now btw....hope this gives some insight
