2007 - 2011 Jeep JK/JKU Wrangler Specific Upgrades
Early model JK/JKU Wranglers equipped with an automatic transmission require an upgrade from the 42RLE. Bruiser has elected to incorporate the NAG-1 722.6/W5A580/WA580*** in our conversion. This upgrade includes a transmission, torque converter, wiring harness, and a performance tuned TCM. Along with the upgraded transmission, a new center console and automatic transmission shifter assembly are provided. This allows the driver access to the late-model tap shift option and updating the OEM software to include PRNDL display functionality on the OEM instrument cluster. Cruise control and auto start features, if equipped, are retained after the conversion.
This compact 5-speed automatic transmission is rated at 580 ft-lb torque input capacity. It has been used in a wide range of vehicles including the Dodge Challenger, Chrysler 300 SRT8, Porsche, Mercedes-Benz Sprinter, Dodge Magnum SRT8, and the supercharged Jaguar X308. A performance tuned TCM is provided with each engine conversion system.

Being in the off-road industry myself, I am very picky about where my Jeep is worked on. Add to that the major work of an engine swap and you quickly realize that trust in the shop is EVERYTHING! Jeff and the crew are at the top of their game! The attention to detail is unmatched and the quality could not be any better. Simply put... they know what they are doing. Add to that the friendly service and you have a winning combination. Thanks again guys!
Jeff, I am really enjoying this Jeep! The attention to detail, knowledge base, advice and professionalism you provided in helping me put this together “the right way” was invaluable. The turn around time was amazingly fast and your conversion product is top notch. I now have all the power I need to do the things I want to do in style. I get a dopamine rush every time I hit the gas pedal! Tons of fun! Many thanks to you and your team in helping me with this build. Proud owner Nick Holman Oakton, Va andNaples, Fl
I've been a Jeep enthusiast most of my life, so when it came to building my "forever" Jeep I knew that finding the right builder was everything. From my very first interaction with Bruiser I felt like much more than a client. I immediately felt like I had a friend in the industry who was helping me fulfill my vision to create a fully customized, one off, SEMA worthy rig. Having a family of 6 a stock JKU just doesn't get it done, especially when it comes to camping off grid and exploring remote areas as my family and I often do. Bruiser worked with me every step of the build from concept to completion. They steered me away from pitfalls and educated me on innovative ways to achieve what ended up being one of the most amazing builds I have ever been fortunate enough to stand beside, and I...
My name is Tygh Brogdon, I called Bruiser Conversions to make me a custom built "one of a kind" Jeep JK Crew. I am a picky person and wanted everything perfect, from the factory rake, to the axles, to the wheels, to the tires, to the interior, to the overall height! You see how picky I am? I had an entire checklist of items that I wanted accomplished. Jeff invited me down and assured me that he could and would do his best to achieve everything I was looking for. I showed up at his shop with a brand new 2014 Jeep Wrangler Unlimited, it had 1,100 miles on it. He was a bit surprised at some of my requests but low and behold HE DELIVERED!! I was communicating with him once or twice a week until the project was complete and then more often as the delivery date neared. He delivered to my door...
As a manufacturer of Jeep parts, our company Jeeps are our sales tools. We are very careful when choosing the modifications we make because our vehicle's performance is a direct reflection of our company when on the trail. It is of paramount importance that our vehicles are on the cutting edge and mechanical failures are kept to a minimum. So when the time came to upgrade the power plant in one of our 2014 JK with a reliable and powerful LS motor there was only one company in the United States to call, Bruiser Conversions. What Jeff and his team were able to do in 6 days is mind blowing and the finished product is FACTORY perfect. Every nut and bolt checked and not a single issue. We would recommend Bruiser and Jeff's entire team to anyone in the market who demands excellence in perform...
