On this update, the 2015 Rubicon has had both Spicer Ultimate Dana 60 axles and the Rock Krawler 5.5" Stage II Rock Runner long arm kit installed, and the new brackets have all been added and painted. The transmission has been re-installed, and the new custom HEMI is ready to be dropped in! The wheels and tires shown here are just rollers, but give a nice idea of how the Jeep will sit when complete, in addition to showcasing how wide the 8-lug Dana 60 axles are in comparison to the stock Rubicon Dana 44s.
The 6.4L HEMI engine for this build, below, customized by Arrington Performance, was stroked and bored out to 7.3L. The engine features all new internals, and has an average horse power rating of 649, with a peak of 702 horsepower at 5800 rpms, and provides 655 pounds of torque. To help ensure that the engine receives adequate amounts of fuel on lengthy off road excursions, a 20 gallon GenRight fuel cell will be added. Meanwhile, the 5.38 gears inside the Dana 60 axles will assist the engine in turning the 40" tires, and the factory Rubicon locker switches will hook right up to the new axles, allowing for a no hassle installation!
Stay tuned for more in the next update!
