The Ford Racing 3.73 Ratio 8.8in Ring and Pinion Set fits the 2015-2025 Ford Mustang GT and delivers quicker acceleration through optimized gear ratios.
Engineered and tested by Ford Racing for maximum performance in the 8.8in rear differential.
Product Overview
This ring and pinion set swaps the factory gears for a 3.73 ratio, trading top-end for stronger off-the-line response and improved throttle feel.
Finished in a black oxide coating for corrosion resistance, the gears are built to handle the demands of the S550 and S650 Mustang GT platforms.
Note: this part is designed and intended for competition use only and should not be installed on a vehicle driven on public roads.
