USA Standard Ring & Pinion Gear Set For Ford 8.8in in a 5.13 Ratio

Enhance Track Performance. The USA Standard Ring 5.13 Ratio Gear and Pinion Kit levels up your Mustang’s torque for faster off-the-line acceleration. If you regularly take your Ford drag racing, then higher acceleration numbers are exactly what you need. It’s important to remember that while a higher gear ratio does translate to faster acceleration, this is achieved at the expense of fuel economy and top speed. Manufactured from heavy-duty 8620 triple-alloy steel that’s heat-treated, for superior strength. The ring and pinion gears are then precision-machined for a true fit resulting in smooth operation. This heavy-duty construction makes for a really tough gear set that can take the kind of high-pressure driving associated with the track. Installation by a Professional Highly Recommended.
