Description

The USA Standard Gear ZG D70-373 is a replacement ring and pinion gear set specifically engineered for the Dana 70 differential, offering a 3.73 gear ratio for optimized performance. This set is constructed from durable steel and features a 10.50" ring gear diameter, a 29-spline pinion, and requires 12 ring gear bolts for installation. Each set is subjected to thorough in-house quality evaluations, including dimensional checks, material testing, and fitment verification, ensuring a reliable and high-performing component for your drivetrain. While offering a cost-effective alternative to other manufacturers, USA Standard Gear ring and pinion sets are noted as not being recommended for quiet-running vehicles. They come with a standard one-year warranty against manufacturing defects.
