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...
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 ...
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...
Jeff I want to personally thank you and your awesome crew at Bruiser Conversions for all the work and help with our OX Locker project JK. Even for the work we did ourselves, drawing from your experience has been a big help and time saver, not enough guys like you in the business. FYI, recently I had conversation with Tom the owner over at PSC Motorsports about how happy he was with the LS3 conversion you did on his JK, he convinced me to pull the trigger on it. Looking forward to topping this project off with your LS3 conversion.
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...
