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 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...
I decided to go with the Bruiser Conversions LS3 conversion kit after the turbo on my 3.6 factory engine blew up. I am so glad that I did, the engineering is unbelievable, everything is "plug & play". The engine and every piece around the engine fits perfectly, plus no more turbo lag!!! My friend and I did the complete job of removing the old engine and installing the new LS3 motor in 3 8-hour days. With a turn of the key it started right up and purred like a kitten. After driving it for 400 miles, I changed the oil and then drove it down to Florida, 1500 miles in 24 hours with no problems. Everybody that sees the engine compartment says that it looks like it's from the factory. When I'm asked where I got it from of course I tell them Bruiser Conversions in Cleartwater, FL. I highly rec...
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!...
I have known Jeff for 7 years, so when it was time to build my 2014 JKU into the LEGEND2.0 with a LS3 480 HP hot cam he was my first call for engine swap advice. Being 10 hours apart, I planned to have the work done closer... but when Jeff said they could do an LS swap in a week, I had to put it to the test. Anyone that could swap that fast with confidence clearly has their ducks in a row. Sure enough, a week later I was headed down to pick her up! Jeff walked me through the numerous custom machined components proprietary to his conversions; some serious hardware! His engineering, his team, and their overall commitment to quality all came through. Doing burnouts as soon as I got back to Charlotte! Thanks Jeff!
