Mopar Performance Transmissions
Get the most out of your powerhouse engine with one of our custom, hand-built Mopar performance transmissions. Enjoy lightning fast shifts and minimal drivetrain power loss with Gearstar’s Mopar performance transmissions. These transmissions are reliably capable of handling up to 1100 horsepower and 1100 ft-lbs of torque.
Unlike other Mopar performance transmissions, our transmissions are built by one master technician from start to finish. This level of intimacy with your transmission insures that they are mindful of your individual requirements and project needs throughout. Before a transmission leaves our facility, it is dyno tested for the equivalent of 100 miles to insure that it is in proper working condition.
