Ring & Pinion Ford Super 8.8in 4.88 Ratio

The Richmond Ring & Pinion Ford Super 8.8 inch 4.88 Ratio is a precision gear set engineered for high-performance rear axle applications in Ford 8.8-inch differentials. This 30-spline ring and pinion kit delivers the aggressive gear reduction needed for enhanced acceleration, making it the choice for off-road recovery, drag racing, and serious off-road driving where low-end torque and quick throttle response are critical.

The 4.88 ratio represents a significant step down from stock configurations, multiplying engine torque approximately 4.88 times at the wheels. This specification excels in scenarios demanding maximum pulling power—steep terrain recovery, heavy towing, or launch performance where conventional gearing falls short. The 30-spline count ensures compatibility with modern Ford 8.8-inch axle shafts while distributing load across sufficient tooth engagement for durability under stress. Richmond's manufacturing standards ensure proper tooth contact pattern and backlash for reliable long-term operation in demanding conditions.

This gear set is purpose-built for builders and enthusiasts upgrading Ford 8.8-inch rear axles in trucks, Mustangs, and specialty vehicles. Whether preparing for rock crawling, improving towing capability, or optimizing quarter-mile performance, the 4.88 ratio closes the gap between engine output and wheel speed. Installation requires proper axle work and gear setup procedures—backlash, carrier bearing preload, and ring gear runout must be verified to manufacturer specifications. Weighing 20.65 lbs, the complete kit integrates easily into existing 8.8-inch housings.
