High-Performance Ring and Pinion. The EXCEL from Richmond 10.50-Inch Rear Axle Thick Ring and Pinion Gear Kit with a 4.88 gear ratio delivers a durable and precise gear set designed specifically for rear axle assemblies equipped with GM 10.5-inch 14-bolt differentials. This kit upgrades the gear ratio to 4.88, improving torque multiplication and vehicle performance under heavy load and towing conditions.

The robust pinion gear features 30 splines and a 1.75-inch shaft diameter, ensuring reliable power transfer. The gears have a standard ring gear rotation and are designed to match GM’s 10.5-inch differential case, promoting longevity and consistent performance.

Ease of Installation. Installation requires mating to a compatible 14-bolt GM 10.5-inch rear differential housing and a differential carrier with a 4.10 or lower gear ratio. This gear set is a direct replacement designed to fit existing bolt patterns without any drilling.

Warranty Coverage. This gear kit is backed by a 1-year or 50,000-mile warranty, providing assurance of quality and durability under normal operating conditions.

Application Fitment. Specifically designed for 2007-2018 Silverado 2500 HD models, ensuring proper compatibility and performance when upgrading or replacing the rear differential ring and pinion assembly.
