Description

The USA Standard ZG GM14T-538T is a ring and pinion gear set specifically engineered for GM 10.5-inch 14-bolt truck axles. This set boasts a 5.38 gear ratio and is designed as a thick gear, making it compatible with carriers designed for 4.10 gearing and numerically lower ratios. USA Standard Gear is committed to providing reliable drivetrain components. Their ring and pinion sets are manufactured to exceed OEM specifications, undergoing rigorous in-house quality evaluations to ensure they meet dimensional, material, and fitment standards. This particular set features a 10.50-inch ring gear diameter, a 30-spline pinion, and requires 12 ring gear bolts for installation. The product is backed by USA Standard Gear's standard one-year warranty against defects. Customers can also benefit from free ground shipping within the continental United States.
