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!
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...
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 met Jeff Garland at Easter Jeep Safari in 2015. I had an LS conversion done on my 2012 JKU by another company with a laundry list of issues, and was looking at one of Bruiser Conversions swaps. Jeff leaned in and began to tell me how wonderful the LS swap was. I was less than responsive as he explained how wonderful his swap was. I explained that I already had the swap done by another company, and was less than impressed. Much to my surprise Jeff described several of my issues to a "T" without me telling him anything. As we visited Jeff told me how bad he felt about my experience, and how he could correct the issues. I swallowed hard, and put my trust in one more individual who said that they could make it work. Jeff arraigned shipping, which is no easy task from where I lived, and th...
I've got a 430hp LS3 installed in my 2012 JK and I love it! I'm running 37's on one ton axles and the factory V6 was not enough to move the thing down the road. I found myself not wanting to drive my Jeep anymore... Until I found Bruiser Conversions. Their LS3 conversion woke the Jeep up and turned it into a monster!!! I daily drive my Jeep now because I enjoy driving it so much. It sounds and feels amazing. The most fun part is red light racing little sports cars and seeing the look on their faces when you blow the doors off them in a lifted Jeep. The most amazing part of the conversion, however, is how it just works. All functions work as they did from the factory, there aren't any funny warning lights or messages on the dashboard. The A/C blows cold. The factory tap shift works. Noth...
