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!
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...
Jeff I want to personally thank you and your awesome crew at Bruiser Conversions for all the work and help with our OX Locker project JK. Even for the work we did ourselves, drawing from your experience has been a big help and time saver, not enough guys like you in the business. FYI, recently I had conversation with Tom the owner over at PSC Motorsports about how happy he was with the LS3 conversion you did on his JK, he convinced me to pull the trigger on it. Looking forward to topping this project off with your 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 andNaples, Fl
In the last 10 months Dixie 4 Wheel Drive has installed 6 Bruiser Conversions LS3 "Do It Yourself Kit" motor conversions. At first we didn't know much about Bruiser Conversions since we are from Utah and they're from Florida. I had heard a few good things about Bruisers, but usually East coast service is hard to keep in touch with. However, with Bruisers it was different. From a shop stand point, we were excited to hear that their motor conversion kit was one of the best JK V8's kits on the market. Since we had done several different Hemi and LS conversions before, we were anxious to install the "Do It Yourself Kit" into our 2015 SEMA build. Once the motor conversion showed up, we were super excited to open the crate up and see the install kit. The wiring harness and front accessory dr...
