Description

The USA Standard Gear ZG D80-411T is a direct-fit ring and pinion gear set engineered for the robust Dana Spicer 80 differential. This set provides a 4.11 gear ratio, offering an upgrade or replacement for vehicles requiring enhanced performance or a correction in gearing. Constructed with durability in mind, USA Standard Gear ensures their sets exceed OEM specifications through comprehensive quality control. This includes thorough testing for dimensions, material composition, and fitment to guarantee reliability. The ZG D80-411T is specifically designed as a 'thick' gear, making it compatible with carriers designed for 3.73 and numerically lower gear ratios. Key specifications for this gear set include a 11.25-inch ring gear diameter, a 37-spline pinion, and the use of 12 ring gear bolts. USA Standard Gear backs their ring and pinion sets with a standard one-year warranty against manufacturing defects, providing added confidence in your purchase.
