Just like our close ratio gears, the MFactory final drive gears are also cut from the same high quality fully Carburized Forged Nickel-Chromoly Steel while also benefiting from our proprietary heat treatment process. As a result, we are proud to offer enthusiasts the best final drive gears on the market today.

By changing your final gear ratios, you can experience a dramatic increase in acceleration, giving you on average, a 10-15% increase in torque throughout the entire rev-range over the OEM Final Drive.

Take your performance to the next level with the MFactory PRO Series Gears. Recognizing the demand for transmission components that can withstand the extreme shock loads produced during Drag Racing, MFactory Competition Products are proud to offer our range of top-tier competition level gears.

Diamond Cut to exacting tolerances from Forged High-Nickel-Chromium-Molybdenum Steel and put through our own proprietary heat treatment process, the MFactory PRO Series Gears are the pinnacle of off-the-shelf performance gears for today's Sport Compact.

Through the use of leading-edge Solidworks 3D CAD & Cosmos FEA software, our advanced gear geometry helps to increase tooth strength, reduce friction and, most importantly, minimize parasitic drivetrain losses. Transmissions built with MFactory PRO Series Gears transfer, on average, 1-2% more power to the ground over our competitors!

Part of the testing criteria for our gears included extreme hot-lapping and tuning sessions on loaded dynos which ensure that not only are our gears strong enough to handle the shock loads encountered during Drag Racing, they are also durable enough to handle the variable loads encountered during day-to-day Street Driving.

Whether used standalone or alongside our PRO Series Gear Sets, our redesigned PRO Series Final Drive Gears (Semi-Helical) increase drivetrain efficiency and are the final link to fine-tuning your race transmission.
