Improve Off The Line Acceleration.
Is your V8 powered New Edge Pony sluggish off the line? If the answer is yes, it's because of the lower ratio gear and pinion set installed by Ford at the factory. Most 1999-2004 Mustangs came standard with 3.27 gears, which are great for daily commuters who are looking for good fuel economy, but not for the hardcore performance enthusiast who wants rabbit quick acceleration. By upgrading to a set of higher ratio 3.90 Richmond Excel Gears your Mustang will enter its power band sooner which will help improve low end torque and give you the quick off the line acceleration you're craving.Superior Quality.
