MMX 4x4 offers in-house installation as well as other Jeep related services!
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 and larger diameter 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 bolt-on mods (cold air intakes, throttle bodys, etc.) / power adders (supercharger, turbo, etc.), or a combination of the two. It turns out that you can bolt-on 10 to 20 horsepower very easily and fairly inexpensively with out HEMI 80mm throttle body and transition package! You combine this with a good cold-air-intake and you are really talking some serious gains at this point.
