The Excel Ring & Pinion Gear Set Ford 9in 5.67 Ratio is a high-performance differential gear assembly engineered for serious enthusiasts seeking aggressive acceleration and traction in Ford 9-inch differentials. This complete kit transforms your vehicle's drivetrain by delivering a lower numerical ratio—ideal for off-road, drag racing, and street performance applications where quick acceleration matters more than top-end highway speed. Whether you're building a muscle car, off-road rig, or competition vehicle, this Richmond-manufactured gear set provides the mechanical advantage needed for demanding driving scenarios.
The 5.67 ratio configuration features a 28-spline pinion design that maximizes torque transfer while maintaining durability under extreme load conditions. Richmond's Excel line employs precision-machined gearing with optimized tooth geometry to reduce noise, vibration, and wear compared to OEM alternatives. The gear set is engineered to handle the mechanical stress of performance driving, delivering reliable power multiplication that converts engine torque into wheel-turning force. Every tooth is cut to exacting tolerances, ensuring smooth mesh and consistent performance across thousands of cycles. The complete kit includes both ring and pinion gears, ready for installation into your Ford 9-inch housing.
This gear set is purpose-built for Ford 9-inch differential applications and benefits drag racers, off-road competitors, and street performance builders seeking repeatable acceleration response. Installation requires proper differential setup, including backlash and bearing preload adjustment—professional installation or detailed technical knowledge is strongly recommended. The 5.67 ratio excels in quarter-mile runs and tight throttle response scenarios while accepting the trade-off of increased engine RPM at highway speeds. Verify your vehicle's differential compatibility and confirm housing specifications before purchase to ensure seamless integration into your drivetrain upgrade.
