We feel the force of Hauk Designs ‘Rat Rock’ Jeep deep on the Nevada desert

Last time we ventured deep into the realms of the Nevada desert, was when we decided to take a ride with Kenny Hauk owner of Hauk Designs and his mental WWII warbird-styled Tomahauk Jeep. See the full feature right here.

One year later and we are back at the Sema Show and boy did we get a shock at Kenny’s latest beast! I remember the conversation out in the desert last year of this new build, but nothing more was revealed until the Sema Show. This build has been inspired by the rat rod culture, with a twist of Steampunk and Mad Max! The result! Totally radical and it was our ‘Car of the Show’ at Sema last year.

Hauk Design Rat Rock Jeep

So where did Kenny get the idea to build such an insane machine? Well for Kenny, he has a major love for the rat rod scene and wanted to create a machine, that not only could climb rocks, but could also be lowered for daily driving around town. The best of both worlds. The project is based on a 1947 Willy’s CJ2A body from Omix-ADA and has been chopped and stretched to fit a modified YJ frame. The Rat Rock concept was first rendered to get a vision of the finish machine, but as the project was in creation, the build kept evolving.

When Kenny got hold of the Jeep body, he noticed that it was too small for all the modifications and parts he wanted to add. So he decided to stretch it, but then find that the engine and transmission didn’t fit the frame rails. The engine is a Cummins diesel and Kenny entrusted the skills of his friends at Industrial Injections and Turbonetics to help build an old 12V engine that Kenny pulled out of an old school bus. This monster now has over 700bhp and 1200 ft-lb!



When taking a much closer look at the build, you will find influences from various vehicles such as tractors, trucks, firetrucks and even airplane detailing. Take a look at the headlight photo from above, and you will notice awesome details such as the etched skull logos inside the headlight housing. Genius!


We spent so much time just looking at every part of this build, to work out what parts and customisations have been added. Take a look at the windshield glass and it comes from an old house that was torn down and when you take a look at the centre console, you will see that it features 120 feet of steel round bar, a well pump handle shifter and some cool old switches from a 1960’s firetruck.




Make your way to the rear of the Jeep and you will see that cool custom made tailgate and other sections of the interior were cut at a local saw mill. In that process, the actual saw broke and so Kenny decided to used those broken pieces throughout the trim, which can be seen in several areas of the Willy’s body.




One of the ride’s awesome features, is the cool vintage look Kicker Audio sound system by the guys at ‘Sounds So Good Audio‘ in Waynesboro PA, you can see below in that epic chest and also that insane hand-built ram skull steering wheel.



Kenny was truly pleased with how the crowds reacted to the build at Sema, with the offroad guys and also the rat rod guys loving the combination. For us, this is possibly one of the most incredible builds we have ever had the pleasure of capturing in photos and we can’t wait to see what Kenny and his team rolling in for this years Sema Show.
