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.
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!
Like many jeep owners I set out to build the ultimate go anywhere jeep to provide amazing family wheeling excursions. Initially built was a mild mod JKU, however the anemic 3.6L became the 'weak link' so I sough out an engine conversion. After determining the LS3 as the most optimum power plant, I then began to search for a builder/installer and chose a local SEMA Jeep Builder. As I explained to the selected builder, 'there are 2 ways to do things, the right way and the wrong' no in-between. Unfortunately for me that selected builder had very little integrity and built a very expensive paperweight. After those in the Jeep community found out what happened many stepped in to assist with my build. We began an extensive rebuild, and we chose the industry leader in LS3 Conversions, Bruiser ...
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...
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. The crafts...
