MMX4x4 / Modern Muscle Performance HEMI Jeep Builds

2010 Jeep Wrangler JK 5.7L HEMI Conversion by MMX4x4 / Modern Muscle Xtreme

Now this is a rare bird... To say there aren't many 392 HEMI powered Gladiators in existence is somewhat of an understatement. Cristian brought us his daily driver 3.6L v6 powered Gladiator because he was ready for some real HEMI v8 power. Power that he was all too familiar with because he also owns a supercharged HEMI endowed Dodge Challenger...read more...

2010 Jeep Wrangler JK 5.7L HEMI Conversion by MMX4x4 / Modern Muscle Xtreme

Decisions, decisions... So your 2010 Jeep Wrangler JKU Rubicon is now 12 years old and the 3.8L v6 with 190,000 miles on it has seen its better days (We dont think this engine ever had good days to begin with) and its time for you to starting thinking about replacing it or buying a new Jeep.

2018 Jeep Wrangler JL Edelbrock Supercharged 3.6L v6 by MMX4x4 / Modern Muscle Xtreme

Whats the next best thing to swapping a HEMI into your Jeep Wrangler for added horsepower? SUPERCHARGING... Thats right, supercharging your 3.6L v6 pentastar can produce some crazy horsepower numbers rivaling the 5.7L HEMI v8. Some kits can raise the rear wheel horsepower upwards of 360RWHP! The 3.6L v6 is a time tested power plant more than capable of handling some forced induction which means you can have that v8 power for a third of the cost...read more...

2018 Jeep Wrangler JL 3.6L v6 Performance Mods by MMX4x4 / Modern Muscle Xtreme

The 3.6L V6 Pentastar engines in these Jeeps have proven to be a fantastic engine for this platform. That being said, when it comes time to lift your Jeep and throw some 35", 37", or even some 40" tires you will notice a hit on the performance of the engine due to the extra weight of the new shoes! At this point you can take a few different routes to help your engine keep up with the additional load... You could re-gear your front and rear differential (EXPENSIVE), throw on some...read more...

2015 Jeep Wrangler JK 6.4L Big Gas HEMI Build and Edelbrock Supercharged by MMX4x4 / Modern Muscle Xtreme

ALL THINGS HEMI... Even if someone wants us to put a HEMI in a vehicle that doesn't come with one from the factory! William brought us his 2015 Jeep Wrangler JK with the standard 3.6L V6 Pentastar engine in it with the idea that he wanted a supercharged HEMI put in its place. Doing a HEMI swap on a Jeep Wrangler isn't a new concept by any stretch, but throwing in a Big Gas 6.4L HEMI with the idea of putting an Edelbrock Supercharger on it, well thats definitely some uncharted territory... read more...
