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...
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...
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!
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...
When I first heard about V8 swaps into jeeps I was skeptical. I am not a fan of installing things on my jeep that require a lot more maintenance and extra steps to use. After talking with Jeff on the phone he invited me to come up to the shop and see what they do. I was immediately impressed at the welcoming attitude of everyone there as well as the open attitude to have me look around. I took a drive and realized just how well integrated these swaps are. You drive it just like when it was stock. No other buttons to push, no instructions to follow. I brought a 6 speed manual and left with an automatic that looked like it came from the factory on the interior. Tap shift, cruise control. It all works, just MUCH more powerful. That magna flow sound of a V8 and the torque when driving from ...
