As a manufacturer of Jeep parts, our company Jeeps are our sales tools. We are very careful when choosing the modifications we make because our vehicle's performance is a direct reflection of our company when on the trail. It is of paramount importance that our vehicles are on the cutting edge and mechanical failures are kept to a minimum. So when the time came to upgrade the power plant in one of our 2014 JK with a reliable and powerful LS motor there was only one company in the United States to call, Bruiser Conversions. What Jeff and his team were able to do in 6 days is mind blowing and the finished product is FACTORY perfect. Every nut and bolt checked and not a single issue. We would recommend Bruiser and Jeff's entire team to anyone in the market who demands excellence in perform...
My name is Tygh Brogdon, I called Bruiser Conversions to make me a custom built "one of a kind" Jeep JK Crew. I am a picky person and wanted everything perfect, from the factory rake, to the axles, to the wheels, to the tires, to the interior, to the overall height! You see how picky I am? I had an entire checklist of items that I wanted accomplished. Jeff invited me down and assured me that he could and would do his best to achieve everything I was looking for. I showed up at his shop with a brand new 2014 Jeep Wrangler Unlimited, it had 1,100 miles on it. He was a bit surprised at some of my requests but low and behold HE DELIVERED!! I was communicating with him once or twice a week until the project was complete and then more often as the delivery date neared. He delivered to my door...
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...
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...
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 ...
