While our Motive Gear tech support line is available during normal business hours, our calculators will help to get your dragster, funny car, street machine or off-road rig to the next level.

This calculator will help your hot rod or street machine get to the next level without red-lining your engine. The Street Performance calculator is also handy when changing tire sizes on street rods.
