Description

The USA Standard Gear ZGK2175 is a comprehensive rear ring and pinion installation kit engineered for the Dana 80 differential. This kit includes a 4.30 ratio ring and pinion gear set, specifically designed for applications with a 10-bolt rear cover and a 12-bolt ring gear. The 11.25-inch ring gear diameter is a key specification for compatibility. The Master Installation Kit contains all the essential bearings, seals, and small parts required for a correct and efficient installation. USA Standard Gear ensures quality through rigorous in-house testing for dimensional accuracy, material integrity, and proper fitment. The included 4.375-inch OD head bearing is crucial for proper assembly. This package offers a one-stop solution for common differential repairs, providing an affordable and convenient option. This specific kit is compatible with 1999-2016 Ford F-350 Super Duty (Rear) models equipped with a 10-bolt rear cover and dual rear wheels (DRW), and 1998-2005 Ford F-450 Super Duty (Rear) models with the same qualifiers.
