Professional Installation Shops Supported by Modern Muscle Performance / MMX!

These are trusted, experienced, and professional installation shops that we consider to be partners in providing our top of the line parts and services.

***When its time to choose a tuner... All of our supported shops either have tuners or use a specific 3rd party tuner of their choice. We recommend taking the time to do your own research when deciding who will be tuning your vehicle. Our supported shops have all tuned Gen3 HEMI builds with great success, but obviously some are better than others when it comes to certain types of builds. Do your homework, make some calls, and have a clear understanding of what you want out of your hot rod! Communication is key.

Sales Tax:  Sales tax at Modern Muscle Xtreme (MMX) and its subsidiaries is based on State and local requirements. For more information, please reference our Sales Tax Policy page.
