Excel Ring & Pinion Gear Set Ford 9in 5.43 Ratio

The Excel Ring & Pinion Gear Set Ford 9in 5.43 Ratio from Richmond is designed for automotive builders and enthusiasts who prioritize aggressive acceleration and enhanced performance in modified vehicles. This gear set is particularly suited for dedicated track machines, drag racing platforms, or heavily modified street builds where rapid off-the-line response is essential.

Engineered to replace the factory gearset in Ford 9-inch differentials, this ring and pinion set features precision-cut hypoid gears that maximize load capacity and minimize noise under extreme conditions. The 5.43 gear ratio is a steep choice that allows for quicker acceleration, though it may reduce top speed compared to higher ratios. Richmond's manufacturing ensures that these gears meet OEM tolerances, providing reliability for both street and strip applications.

This gear set is ideal for drivers of full custom chassis, tube-frame race cars, or extensively modified street machines. It is designed to handle the demands of high-horsepower naturally aspirated engines, as well as those utilizing forced induction or nitrous assistance. With a weight of 19.4 lbs, it offers a minimal rotating mass penalty while delivering the durability needed for performance applications.
