Converting your 2007-2011 Jeep JK for a GM LS GEN4 engine (07-13 5.3, 6.2) (07-17 6.0) with a 6L80E 6-speed automatic transmission might seem like a complex undertaking. We simplify this powerful upgrade with our premium DIY conversion kit, designed to be as straightforward as possible, getting your Jeep running with enhanced performance and integrated technology.
Our kit features a brand new, 100% plug-and-play harness, eliminating the hassle of modifying or sending in old parts. With minimal wiring needed into your existing Jeep system, installation is remarkably user-friendly. The core of our system is a state-of-the-art CanBus module. This sophisticated technology ensures seamless data communication, effectively creating a factory-style, fully integrated GM engine experience within your Jeep, maintaining all your vehicle’s original functionalities.
This innovative harness merges the Jeep and GM wiring systems into a single, streamlined unit. The engine harness is designed for direct ECU connection via a factory plug at the firewall. The harness is routed behind the engine and under the fuel rails, improving engine bay aesthetics and allowing for the use of factory engine covers. Our under-dash harness integrates the GM accelerator pedal, ALDL, GM fuses and relays, and the EZ CanBus module, all while connecting directly to the main harness.
The result is not only an easier installation process but also enhanced visual appeal and premium quality and durability in your engine conversion.
Advanced Technology for Seamless Integration
What sets our conversion kit apart is the advanced technology we employ to ensure flawless integration. Your Jeep JK, like many modern vehicles, relies on a CanBus communication system. This is a complex network where every component communicates using a specific digital language. GM GEN4 engines and vehicles also utilize CanBus systems, but the crucial challenge lies in the incompatibility between the GM and Jeep CanBus languages.
Our innovative EZ CanBus system acts as a translator. It intelligently processes the GM and Jeep CanBus signals, converting languages in real-time within our EZCanBus module. This breakthrough allows for seamless communication between the two systems. For example, the GM tachometer signal is effortlessly transmitted to your Jeep gauges, eliminating the need for supplementary reluctor rings or external simulator modules. This integration saves significant installation time and greatly enhances reliability. Similarly, the GM coolant temperature signal is directly utilized by the Jeep gauge, further reducing complexity and cost by avoiding the installation of an additional coolant temperature sensor. This sophisticated CanBus integration can be seen as an “Xtreme Obd2 Simulator” in its functionality, providing complete data translation and ensuring all your gauges and systems operate correctly with the new engine, without needing external OBD2 simulation devices.
Further enhancing functionality, our system provides a fully operational PRDNL display on your Jeep dashboard, accurately showing gears 1-6 during TAP shifts. Factory Jeep cruise control switches are repurposed to manage both cruise control and GM TAP shifting, removing the need to modify your shifter or instrument cluster. The cruise control light and check engine light function as originally designed, thanks to the intelligent EZ CanBus module. For automatic Jeep JK models, GM TOW HAUL mode is activated via your O/D off button. The EZ CanBus system includes many more features and is designed to be upgradable for future enhancements.

Enhanced Components for Superior Performance
Aluminum Radiator: Our 52mm direct fit aluminum radiators are engineered to seamlessly bolt into the Jeep JK using factory mounts and hardware, and are designed to accommodate stock fans and the AC condenser. Installation is exceptionally straightforward. The radiator design is specifically matched to the LS engine configuration, featuring correctly positioned inlets and outlets, including a steam port fitting. We offer options for both (TRUCK) and (LS3) engines. The LS3 radiator is tailored to the LS3 water pump, ensuring correct hose positioning and compatibility with readily available over-the-counter upper hoses. Our Truck style radiator is designed for truck water pumps, providing extra clearance for the air intake to pass over the upper hose, which is also a standard part available at most auto parts stores.
AC Hoses: Our AC hoses are direct replacements for the Jeep JK Evaporator at the firewall and condenser connections. They integrate the stock Jeep AC pressure switch and high-low fittings. Designed to fit a GM truck AC compressor mounted in the stock GM lower right engine position, these hoses route neatly along the lower radiator support, providing a clean look under the hood. They are also compatible with aftermarket compressors in the same lower right engine location.
Air Intake: Our air intake kit is constructed from a composite material that effectively reduces heat soak, resulting in lower intake air temperatures compared to aluminum systems. It includes a MAF sensor mount and a breather port, and comes complete with all necessary couplers, clamps, and a high-performance K&N filter. Note: you will need a 15865791 credit card style MAF sensor.
Computer Programmer: We include professional-grade tuning hardware that enables you to read and save your GM ECU-TCM calibration. Simply email us your calibration file, and our expert tuners will create a custom tune tailored to your specific setup, which we will then email back for you to flash into your Jeep.
