Rebel West is in our shop today getting ready for this year's Easter Jeep Safari. In this build, we are using none other than Bruiser Conversion's Stage 1 LS Conversion with 450 horsepower and 450 ft-lb torque. The NAG-1 722.6/W5A580/WA580***, the factory automatic found in the 2012-2017 Jeep JK/JKU Wrangler, remains intact when installing the Bruiser Conversions LS3 engine. This compact 5-speed automatic transmission is rated at 580 ft-lb torque input capacity. It has been used in a wide range of vehicles including the Dodge Challenger, Chrysler 300 SRT8, Porsche, Mercedes-Benz Sprinter, Dodge Magnum SRT8, and the supercharged Jaguar X308. A performance tuned TCM is provided with each engine conversion system.

This turn-key Bruiser Conversions fully integrated LS3 engine conversion system for the Jeep JK/JKU Wrangler maintains the original equipment manufacturers (OEM) functionality of all vehicle systems that were supplied with your vehicle. All systems that were functional prior to the conversion process will be functional after the conversion has been completed, this includes: instrument cluster, indicators, gauges, powertrain control systems, cruise control, hill descent mode, tip start, and tap shift. Our system retains the factory PCM and the Chrysler OBD II port. Bruiser Conversions provides the only fully integrated LS3 engine conversion for the JK/JKU Wrangler.
