Jeep Wrangler JL  HEMI Conversions by MMX4x4!

Here at MMX4x4, we have been installing Gen3 HEMI’s in different vehicles for nearly two decades. If you checkout a hot rod site (www.modernmusclextreme.com) you will find that we literally have hundreds of HEMI builds under our belts, including very famous builds like AZN’s “JeeperSleeper” featured regularly on the Discovery Channel’s “Street Outlaws.”

Here at the MMX4x4 shop, in Southwest Virginia, we have technology here in house that sets us apart from our competition. From a cutting edge HEMI engine building shop, 4 wheel drive capable Chassis Dyno for custom tuning, CNC machine and fabrication shops, and anything else one might dream of when contemplating the perfect shop to convert your Wrangler to a HEMI V8 power house. We have it all, and we cant wait to show you.
