Being in the off-road industry myself, I am very picky about where my Jeep is worked on. Add to that the major work of an engine swap and you quickly realize that trust in the shop is EVERYTHING! Jeff and the crew are at the top of their game! The attention to detail is unmatched and the quality could not be any better. Simply put... they know what they are doing. Add to that the friendly service and you have a winning combination. Thanks again guys!
No Jeep is the same and everybody likes to customize his or hers own. As so did I. I started with a used black stock Rubicon unlimited out of 2012. The reason for this was the new transmission that they introduced that year. After the first upgrades (bumpers, lift and tire's) it was time for the more serious upgrade, an engine swap. When you are pulling a wrangler over the mountains in Colorado with a stock 3.6L V6 engine, you get the feeling you are Fred Flintstone. The nice 2.8L CRD would be a nice help with that, but unfortunately you can only get those in Europe. What to do? We all love the big V8's. So the next trip would be to your local Jeep off-road shop and swap that stock engine for a nice 5.7 or 6.4 Hemi. Now just wait there for a moment. Let's browse the internet for a momen...
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'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...
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 ...
