3.23 Ring & Pinion Gear Set Mopar 8.75

The Yukon Gear and Axle 3.23 Ring and Pinion Gear Set for Mopar 8.75-inch differentials is a high-performance replacement gear set engineered for Chrysler vehicles equipped with the 42 housing configuration. This precision-cut gear assembly delivers improved acceleration and off-road performance by optimizing the final drive ratio for vehicles requiring deeper gearing than factory specifications.

The 3.23:1 ratio represents a moderate gear reduction that balances low-end torque with highway cruising efficiency compared to the 3.55 and 3.73 options available in the Yukon lineup. Yukon's ring and pinion sets are manufactured to exacting tolerances and feature a robust tooth profile designed to handle street and light off-road duty. The 8.75-inch Chrysler differential housing is commonly found in Dodge, Plymouth, and Mopar applications, making this gear set compatible with a broad range of classic and vintage Chrysler platform vehicles. Proper installation requires a qualified technician with differential service experience and appropriate bearing preload tools.

This gear set suits owners upgrading from worn factory gearing, modifying vehicles for improved off-road traction, or restoring Mopar differentials to factory or custom specifications. The 3.23 ratio is particularly effective in heavier vehicles where increased engine revolutions improve throttle response without excessive fuel consumption at highway speeds. Yukon Gear and Axle maintains strict quality control and offers technical support for installation and maintenance questions specific to ring and pinion service.

Mopar 8.75 differentials have been produced across multiple decades with variations in bearing size and case design, so verification of compatibility with your specific vehicle and differential assembly is essential before ordering. Yukon provides detailed cross-reference guides and technical documentation to confirm fitment for your application.
