Ring & Pinion Quick Change Gear 4.12

The Richmond Ring & Pinion Quick Change Gear 4.12 is designed for performance-oriented drivers and gear ratio enthusiasts who require quick differential swaps without the need for complete disassembly of the rear axle assembly. This quick-change design is particularly beneficial for drag racers, circle track competitors, and street enthusiasts who frequently adjust their gearing for varying track conditions or racing classes.

The 4.12:1 gear ratio provides aggressive acceleration and higher engine RPM at cruising speeds, making it ideal for quarter-mile performance and enhancing low-end torque multiplication on lighter vehicles. Richmond's quick-change ring and pinion system features precision-cut hypoid gearing, engineered to withstand sustained high-load conditions while ensuring smooth engagement and minimal backlash. This gear set is manufactured to strict tolerances to endure the shock loads typical of high-horsepower applications.

Best suited for dedicated race vehicles and performance builds, the Richmond Ring & Pinion Quick Change Gear 4.12 allows for flexibility in gear selection, which is critical for competitive racing. The quick-change feature can significantly reduce the time required for gear swaps, although some tools may still be necessary for installation and adjustments, making it a valuable addition for those looking to optimize their racing performance.
