Improve Off The Line Acceleration.
Does your New Edge Mustang spend its days at the track adding a quarter mile at a time to its odometer? If so, you should upgrade to a set of Richmond Excel 4.56 Ring and Pinion Gears. With a much steeper ratio than the factory installed 3.27 gears, these Excel 4.56 Gears are perfect for serious drag racers that are on a quest for faster off the line acceleration and quicker 60 foot times. While 4.56 gears can be used for street applications, they are really intended for drag race use.Superior Quality.
