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'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...
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...
No Jeep is the same and everybody likes to customize his or hers own. As so did I. I started with a used black stock Rubicon unlimited out of 2012. The reason for this was the new transmission that they introduced that year. After the first upgrades (bumpers, lift and tire's) it was time for the more serious upgrade, an engine swap. When you are pulling a wrangler over the mountains in Colorado with a stock 3.6L V6 engine, you get the feeling you are Fred Flintstone. The nice 2.8L CRD would be a nice help with that, but unfortunately you can only get those in Europe. What to do? We all love the big V8's. So the next trip would be to your local Jeep off-road shop and swap that stock engine for a nice 5.7 or 6.4 Hemi. Now just wait there for a moment. Let's browse the internet for a momen...
To make it short and sweet, Jeff and his crew over at Bruiser Conversions hit a homerun with their LS conversion for the Jeep JK! I personally believe it is by far the best LS conversion on the market. When we here at PSC Motorsports decided to do a V8 swap in one of our new 2015 JK's, I knew I wanted a LS3. We have done the Hemi thing in the past and this time I had my heart set on a LS3. So when it came time to pull the trigger on the project we hooked up with Jeff Garland and Bruiser Conversions. He has come up with a very different approach to the JK / LS swap, and it is ingenuous. Fellow off road industry insiders had been telling me how well the Bruiser Conversion works and well, I am a believer! I freaking love this Jeep and it's all due to the flawless LS3 conversion. The crafts...
