Description
High-Performance Ring and Pinion. The Richmond 8.5-Inch and 8.625-Inch Rear Axle Ring and Pinion Gear Kit with a 5.38 gear ratio is designed to replace and upgrade the ring and pinion gears in GM 8.5 and 8.625-inch 10 bolt differentials. It enhances drivetrain performance by providing an optimized gear ratio, which is vital for better torque management and efficiency. This gear set is essential for vehicles requiring a numerically higher gear ratio for improved power delivery, particularly in off-road or towing applications.

Installation. Installation should be performed by a professional or experienced technician. The process typically does not require drilling but requires the use of a notched cross pin (part number 80-0272-1) and careful verification of carrier compatibility for optimal fit and function.
Warranty. This product is backed by a two-year or 100,000-mile warranty, providing assurance of durability and workmanship.
