I want to thank the Bruiser Team for turning my 2004 Jeep TJ into a one of a kind LS3 swapped TJ. After a few phone conversations with Jeff going over what I wanted/needed it was an easy decision to send it out to Bruiser. I had originally planned to just do the LS3 swap, but after visiting the shop and hanging out with the guys for the day checking out all the jeeps under construction, my engine swap quickly turned into a complete redo. The Baja style roll cage/tire carrier turned out awesome! The guys at the shop were very helpful in steering me in the right direction on what additional changes I wanted to add to the build. I have had my jeep back for a week now and it drives so much better than it did before with a hell of a lot more horsepower. It’s definitely a head turner!...
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!
To make it short and sweet, Jeff and his crew over at Bruiser Conversions hit a homerun with their LS conversion for the Jeep JK! I personally believe it is by far the best LS conversion on the market. When we here at PSC Motorsports decided to do a V8 swap in one of our new 2015 JK's, I knew I wanted a LS3. We have done the Hemi thing in the past and this time I had my heart set on a LS3. So when it came time to pull the trigger on the project we hooked up with Jeff Garland and Bruiser Conversions. He has come up with a very different approach to the JK / LS swap, and it is ingenuous. Fellow off road industry insiders had been telling me how well the Bruiser Conversion works and well, I am a believer! I freaking love this Jeep and it's all due to the flawless LS3 conversion.

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 & Naples, FL
I've got a 430hp LS3 installed in my 2012 JK and I love it! I'm running 37's on one ton axles and the factory V6 was not enough to move the thing down the road. I found myself not wanting to drive my Jeep anymore... Until I found Bruiser Conversions. Their LS3 conversion woke the Jeep up and turned it into a monster!!! I daily drive my Jeep now because I enjoy driving it so much. It sounds and feels amazing. The most fun part is red light racing little sports cars and seeing the look on their faces when you blow the doors off them in a lifted Jeep. The most amazing part of the conversion, however, is how it just works. All functions work as they did from the factory, there aren't any funny warning lights or messages on the dashboard. The A/C blows cold. The factory tap shift works. Noth...
