This Jeep Wrangler JKU build is starting to evolv into a beast. When we were first approached about building a new JKU we started looking at the big picture. The customer wanted an all out Jeep build with custom axles, huge tires, and lots of power. We realized most of the Jeep Wrangler would not be used so why spend an enormous amount of money on a newer 4x4 JKU. We instructed him to purchase an early model JKU that was only 2wd. Since the 2wd models are undesirable as are the motors they are a tremendously more cost effective So as the search began it didn't take long for a good deal to show up and the build you see below began its new life. Lets make this easy and start with a bit of the build list.
This JKU will be the platform for many new Motobilt parts to come. One of them is our new Jeep JKU Rocker Guards.You can find more information on the new Motobilt Jeep Wrangler JKU rocker guards by clicking here! Trail Ready 17x8.5 HD beadlocks on 41.5" Irok Radials were chosen to roll this beast around. A GM 14 bolt rear axle in back handles these massive meats. A Motobilt GM 14 bolt rear race truss, diff cover, and disc brake kit were added to finish up this bullet proof axle.We will update this post so keep coming back. Update 9/27/2017 The LS1 conversion requires you to remove the factory mounts from the frame before a new set of mounts can be installed. Instead of trying to reinvent the wheel with a one off set of mounts we contacted some of the best in the business over at Novak Adapters. A simple phone call and a couple days later we had a set of GM Generation III & IV V8 Engine Mounts at our door.
