Description

The USA Standard Gear ZG F9.75-411-11 is a rear differential ring and pinion gear set designed to upgrade your vehicle's performance, suitable for towing, hauling, racing, and off-roading. It addresses the decrease in acceleration often experienced when larger tires are installed, restoring lost performance and improving overall efficiency. This gear set features a 9.75-inch ring gear diameter, 12 ring gear bolts, and a 31-spline pinion. It is manufactured using the latest designs and manufacturing technologies, ensuring durability and ease of installation. The product is backed by a one-year warranty against manufacturer defects. Installation of new gears in your axle typically requires common hand tools, a hydraulic press, and a dial indicator. It is also recommended to acquire a master overhaul kit, which includes necessary components like new bearings, seals, shims, and a pinion crush sleeve for reliable and quiet operation.
