2020 – Current | 550HP 6.6L LX3 V8 engine and stronger 8-speed conversion for Jeep Gladiator JT

Bruiser Conversions offers a fully-integrated, powerful 550 hp, 6.6L LX3 V8 engine and stronger 8-speed conversion for Jeep Gladiator JT. Bruiser has combined the legendary power and reliability of the GM Performance small-block V8 engine family with the adventurous go-anywhere attitude of the Jeep platform.

Fully Integrated:

The Bruiser Conversions’ LX3 V8 engine and stronger 8-speed conversion for Jeep Gladiator JT 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 (cruise control, hill descent mode, tip start, and tap shift) will work in the same manner as they did when the vehicle rolled off the assembly line. Factory functions are fully integrated with the Bruiser LX3 V8 engine and stronger 8-speed conversion for Jeep Gladiator JT system.

Transmission:

The OEM Chrysler Torqueflite 8 automatic transmission (ZF design) 850RE in the JT Gladiator has a rated input torque capacity of 500 N-m (370 ft-lb). Bruiser has developed a fully integrated transmission upgrade using the stronger Chrysler Torqueflite 8 automatic transmission (ZF design) 8HP75. The stronger 8HP75 has a rated input torque capacity of 750 N-m (550 ft-lb). Historically, this transmission has been in use across the MOPAR fleet behind the 5.7L and 6.4L Hemi engines. Consequently, it has a proven history of performance and durability.  Bruiser engineered the necessary adapters to connect the Bruiser Power LX3 performance crate engine conversion system with the 8-speed 8HP75 transmission.  As a result, all transmission functions are integrated with the Jeep’s OEM software and control systems.

How do you make it run off of a Chrysler computer?

We start off converting the engine to our own reluctors to communicate with the Chrysler computer. Most of the internal sensors and everything external on the motor that communicates with the ECM are Chrysler based. By doing that, it gave us the capability of maintaining all of the Jeep factory options for the vehicle as if it were coming off the showroom floor.

LT engine conversions have replace the LS engine swap

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. It’s a 6.6L torque monster without the tuning and RPM limitations of factory direct injection.

Bruiser Conversions developed this complete, bolt-in, and integrated LX3 V8 crate engine with an upgraded 8-speed transmission kit for your JT project!

**This conversion is intended for off-road use only**
