Each of Motive's gears are CNC machined from ultra-tough 8620 gear steel that can handle up to 600 rear wheel horsepower and all of the massive forces of hard launches. The steeper gear ratio, while improving performance, will hurt the Mustang's mileage. For purely street-driven Ponies, we recommend using Motive 3.73 Gears that offer milder acceleration gains without as much drain on your gas.
Differential gear systems involve complex a fairly complex installation process. We strongly advise professional installation and the purchase of a Motive Master install kit that includes bearings.
