Why you built it: I wanted to build a super light 2 door JK crawler that handled well enough to daily drive with good ride quality on big tires. We met our goal as this Jeep was on 40s and drove down the highway at 75 mph with zero vibes and handled great. A blast to drive and boy did it turn heads.

What you would do differently: I would have hung on to this Jeep as well and added coilovers and later transformed it into a camping rig.

    Since you’ve built a few of these JKs, how do you like the 2-door versus the 4-door for off-roading as well as just plain driving to work?

    Do you know the total weight as it sits in the pics?

      I do not know the total weight. With 5.13s and a stock engine on 40″ tires the Jeep had some get up and go. it turned out to be exactly what I was going for. Got 19 mpg on the highway as well loaded with gear.

    I feel like the 2 doors are easier to wheel and fit my personal preference a little better I think they’re the perfect trail rig. I would’ve liked to stretch this jeep more, lower it and add more features for storage and make it a cross between hard core trail rig and camping rig which is more of what I’m getting into nowadays.

    I really liked my 2 door driving to work as well, it drove great on the highway, was comfortable and just a blast to drive.
