Interesting build, looking good so far.
Is that poor little jeep going to be able to hold that 750lb motor?

Very nice build... Now this is going into a jeep? Lol my goodness this is going to be a tight squeeze!! The weight on the front end... what type of Axles are you going to be running? I would suggest something on the lines of a Dana w/ 4.10 gears. Your putting a 5.5 lift on the front and rear correct? Is it going to be coil over springs? Do you know the Gross weight on that engine after its all said and done with your add-ons? You will have to cut your hood and put a very large Cowl on there. with real air intakes. I am sure you have measured your clearance?

You don't want taller soft springs, you want the correct height spring in a stiffer spring rate. Old Man Emu and a few other companies sell different spring rates for heavy bumpers etc. Its about a 300lbs difference to a stock 4.0L
Lots of info in this thread on different brands and spring rates
