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!...
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 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!
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 ...
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!
