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...
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...
January 3, 2015 I had a LS3-430HP Corvette motor installed in my Jeep by Bruiser Conversions. Many have asked how I like it, how long did it take, what's it like, how was fit and finish, etc. Saturday January 3rd I drove from Naples to Clearwater. Met Jeff at Jeff's Jeep Yard/Bruiser Conversions where I was given a complete tour and filled with a ton of knowledge. Jeff will blow your mind with his passion and expertise! Left the Jeep in Bruiser's hands and returned to pick it up on Friday Jan. 9th. Yes, that is correct - One week for the conversion. And not just the conversion, they painted my rear wheel wells. Needless to say, I was like a kid in a candy store ready for the first drive! I'm pretty particular about cleanliness and was pleasantly surprised to see how clean the jeep was w...
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 ...
