Bruiser Conversions now offers our signature, fully integrated, LS3 engine conversion system for the 2018 Jeep JL Wrangler. Bruiser has yet again combined the legendary power and reliability of the GM Performance LS family of engines with the go-anywhere capability of the Jeep Wrangler.
Bruiser's LS3 engine conversions system for the Jeep JL Wrangler maintains the original equipment manufacturers (OEM) functionality of all vehicle safety, comfort, and on-board diagnostic systems. All instruments, indicators, gauges, and powertrain control systems will work in the same manner as they did when the vehicle rolled off the assembly line. Cruise control, hill descent mode, tip start, and tap shift systems are fully integrated with the Bruiser LS3 engine conversion system.
The ZF Torqueflite 8 automatic transmission, when equipped in the JL Wrangler, has a rated input torque capacity of 561 ft-lb. This transmission has been in use across the MOPAR fleet behind the 5.7L and 6.4L Hemi engines and has a proven history of performance and durability. Bruiser has engineered the necessary adapters to connect the Bruiser GM Performance LS3 engine conversion system with the factory installed 8-speed transmission; all transmission functions have been integrated with the Jeep's OEM software and control systems.

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...
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!...
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!
January 3, 2015 I had a LS3-430HP Corvette motor installed in my Jeep by Bruiser Conversions. Many have asked how I like it, how long did it take, what's it like, how was fit and finish, etc. Saturday January 3rd I drove from Naples to Clearwater. Met Jeff at Jeff's Jeep Yard/Bruiser Conversions where I was given a complete tour and filled with a ton of knowledge. Jeff will blow your mind with his passion and expertise! Left the Jeep in Bruiser's hands and returned to pick it up on Friday Jan. 9th. Yes, that is correct - One week for the conversion. And not just the conversion, they painted my rear wheel wells. Needless to say, I was like a kid in a candy store ready for the first drive! I'm pretty particular about cleanliness and was pleasantly surprised to see how clean the jeep was w...
