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.
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...
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 ...
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...
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!
