Description

The USA Standard Gear ZGK020 is a comprehensive differential re-gearing package designed for specific truck applications. This kit includes both front and rear ring and pinion sets, as well as the most complete master kits available, allowing for a full re-gear of your vehicle's differentials with a single part number. The kit is engineered for standard rotation Dana Spicer 60 and 1988 and down GM 10.5" 14-bolt truck axles. It features a 4.88 gear ratio, which is suitable for a 4.10 and down carrier with its included thick rear gear set. This combination ensures durability and optimal performance for your drivetrain. This package aims to simplify the re-gearing process by providing all necessary components in one convenient kit. Proper installation is crucial for the longevity and performance of the differential components.
