Bruiser Conversions developed the world’s only fully-integrated LS Swap Kit for Jeep JK vehicles.
A Bruiser Conversions’ engine swap kit unites both Chrysler and GM components to create a single, seamless system. We engineered a system for an LS Swap into a Jeep JK that connected all the factory Chrysler components with specific GM components. Therefore, enabling them to communicate through the Chrysler PCM (no parasitic GM controller used) and the one factory OBD2 port. There are no micro switches in the tap shifter, the cruiser control works, and all the gauges function with no dash lights!
A Better LS Swap for Jeep JK : LX3 Engines have replaced the LS3
GM has released their best small-block V8 yet with the Gen-V LT engine family. Therefore, the production of GM LS engine blocks has all but halted. The LS3 crate engine from GM Performance is no longer available. No worries! Bruiser Power Solutions has designed, tested, and released the LX3 crate engine, an LT-based engine with port injection using a Gen-IV operating system that pumps out the power. If you own a Jeep Wrangler JK (JL, or Gladiator JT), Bruiser Conversions has developed a complete, bolt-in, and integrated V8 engine swap kit for you!
- New LX3 crate engine (GM Performance LT based)
- Performance tuned PCM
- Performance tuned TCM
- Engine to NAG-1, or 8HP, or Temec Transmission
- Crossmember and Bolt-in Motor Mounts
- OEM quality Wiring Harness
- Cold Air Intake w/ K&N Filter
- New A/C Hoses
- New Radiator & Heater Hoses
- Battery Tray & TIPM Relocation Bracket
Be 8 times happier with an 8-Speed Transmission in your jk!
Why upgrade to the 8 Speed Transmission?
The 8HP is a stronger transmission that can handle more power. For the early model (2007 – 2011) Jeep JK, that factory 4-speed transmission (42RLE) is not designed for V8 power and it must be replaced. For the late model (2012 – 2018) Jeep JK, the 5-speed NAG-1 transmission became the factory installed option. The Mercedes designed NAG-1 was much better than the 4-speed and has done well with the V8 power. However, the 5-speed limits the drivability and efficiency. Also, they are getting up there in mileage and the worn parts are only going to wear out even faster with a V8! Jeep provided us an opportunity with the new 850RE Gen2 8-speed transmissions (designed by ZF) in the Wrangler JL. RAM was also using stronger (ZF designed) 8HP 8-speed transmissions in 4X4 trucks! In true Bruiser fashion, we developed an integrated system to use these amazingly better 8HP 8-speed transmissions in our kits for Jeeps. Additionally, during our R&D, we were able to dial in the shift points of the transmission to maximize the performance coming from the LX3 V8 engine in the optimal RPM range. Now, we can provide you with improved strength, shift quality, and efficiency (including fuel economy). Hint! Hint! This can also be beneficial to those who have larger than stock tire sizes!
