Bruiser Conversions fully integrated LS3 engine conversion system for the Jeep JK/JKU Wrangler maintains the original equipment manufacturers (OEM) functionality of all vehicle systems that were supplied with your vehicle. All systems that were functional prior to the conversion process will be functional after the conversion has been completed, this includes: instrument cluster, indicators, gauges, powertrain control systems, cruise control, hill descent mode, tip start, and tap shift. Our system retains the factory PCM and the Chrysler OBD II port. Bruiser Conversions provides the only fully integrated LS3 engine conversion for the JK/JKU Wrangler.
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.

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 have had the pleasure of wheeling with the Bruiser team for many years, as well as driving their conversions. The trucks handle great both on and off-road and their power is something you just won't find anywhere else. People can't help but look, gawk and ask a ton of questions because they are so unique in both their looks and performance. Plus, the entire team is made up of some of my favorite people to be around with due to their positive attitudes and constant desire to make everything function at the best of it's potential.
Savvy Off Road is know for their winning KOH Jeeps and lightweight armor. When we chose to install a LS3 in our 2014 JK Unlimited, there was only one choice. Bruiser Conversions! The LS3 conversion for the JKU is the best available kit. No double computer or harness to take up space and maintain. We have seen our fair share of double harness kits leave the owners very frustrated. The batteries would go dead on them frequently and not all of the features of the JK were available like OEM. The Bruiser Conversion on the other hand uses the OEM Jeep computer and transmission so everything functions like it is from the factory except you now have 430+ HP. We install the best of the best in everything we do. Bruiser Conversions is the only way to go!
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...
I have known Jeff for 7 years, so when it was time to build my 2014 JKU into the LEGEND2.0 with a LS3 480 HP hot cam he was my first call for engine swap advice. Being 10 hours apart, I planned to have the work done closer... but when Jeff said they could do an LS swap in a week, I had to put it to the test. Anyone that could swap that fast with confidence clearly has their ducks in a row. Sure enough, a week later I was headed down to pick her up! Jeff walked me through the numerous custom machined components proprietary to his conversions; some serious hardware! His engineering, his team, and their overall commitment to quality all came through. Doing burnouts as soon as I got back to Charlotte! Thanks Jeff!
