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.
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...
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...
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.
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 ...
