I very much doubt you would get an extra 1.5 inches. The spring rate on the Mapor 3.6 is about 140 front and say about 150 rear (pulling from memory so i may be off a bit on these numbers...but theory stands) Meaning that 140 / 150 lbs will compress the spring one inch. That means to sit one inch lower overall you would need to add 580lbs to the jeep. The diesel is only 400 lbs heavier than the 3.6. Meaning you could expect to see about 3/4 inch extra compression on a diesel running 3.6 springs. So if you have a 3.6 two inch lift you could expect about 1.25 inches of actual lift on the diesel. So the way i read what you are saying is you need 1.25 + an additional 1.5. So about 2.75 inches overall. No two inch lift is going to gain you 2.75 inches. You would need to move up to an aftermarket 2.5 or 3 inch. Evo and RK are both making springs that are diesel specific and within that range.I think that is Skyjacker lift. I would like to see how much more clearance I get if I remove my 3.6l Mopar lift and install Mopar 3.0l diesel kit. If it is worth $1,500. If it is at least 1.5" I will spend the money and do it.
