3.55 Ring & Pinion Gear Set Mopar 8.75

The Yukon Gear and Axle 3.55 Ring and Pinion Gear Set for Mopar 8.75-inch differentials is a high-performance upgrade designed for vehicles requiring improved acceleration and engine efficiency. This ring and pinion set delivers a 3.55:1 ratio with a 10-spline pinion, making it an ideal choice for owners seeking stronger low-end torque multiplication without sacrificing highway cruising capability. The 8.75-inch Mopar differential is commonly found in mid-size and full-size Chrysler, Dodge, and Plymouth vehicles, and this Yukon gear set is engineered to factory specifications for seamless installation.

The 3.55 ratio represents a moderate step up from stock gearing on many Mopar 8.75 applications, translating to faster acceleration off the line while maintaining reasonable fuel economy on the highway. The 10-spline pinion design ensures reliable torque handling and compatibility with OEM and performance driveshafts. Yukon manufactures these gear sets to precise tolerances, with each component inspected and tested before shipment. Installation requires professional differential service to ensure proper bearing preload, backlash adjustment, and gear mesh, which impacts longevity and performance.

This gear set is suited for street-driven vehicles, weekend cruisers, and lightly modified Mopar platforms where owners want noticeable acceleration improvement without extreme ratio penalties. The 3.55 ratio works well for engines ranging from stock displacement to mild performance builds. It's popular among classic Mopar enthusiasts and owners of A-body, B-body, and E-body vehicles equipped with 8.75-inch differentials. Proper installation by a qualified technician ensures years of reliable service and optimal gear life.
