JK HEMI V8 (5.7L or 6.1L) Conversion Package

JK HEMI V8 Builder Kit. Clean, simple, and complete.

If you’ve dreamed of owning a HEMI powered JK but are more of a Do It Yourself type,  AEV makes it simple.  Designed for shade tree mechanics and professionals alike, AEV’s HEMI Builder Kit includes everything you need to complete the swap with factory like results.  All the parts included with this kit are manufactured by Tier 1 suppliers to Chrysler, meaning that these parts are coming out of many of the same factories as the parts on your Jeep! 

The Standard AEV JK HEMI Kit will get you started with our exclusive “no measure” engine and transmission mounts, Radiator, Computer, Plug and Play Wiring Harness, Coolant bottle, and all the plumbing - Three new air conditioning hoses, Two power steering hoses, and a new fuel line, as well as Radiator Hoses and even Clamps are provided.

AEV’s Premium HEMI Kit adds a custom Flowmaster stainless steel exhaust, Catalytic Converters, a Chrome Exhaust tip, Heavy Duty Transmission Cooler and an AEV ProCal Module so you don’t need to go to a dealer for the initial setup, the ProCal will enter the VIN and allow you to program the throttle at home, not to mention all the normal ProCal features like setting your speedometer, gear ratio, TPMS thresholds, and have a high idle for winching operations.
