7.5" Reverse Rotation Ring and Pinion Gear Set 4.56 Ratio

The USA Standard Gear ZG T7.5R-456R is a high-performance ring and pinion gear set engineered for Toyota 7.5" reverse rotation differentials, offering a 4.56 gear ratio. This set is ideal for vehicles used for towing, hauling, racing, or off-roading, and can help restore acceleration lost from adding larger tires, making the truck run more efficiently. Changing to this higher ratio gear set can also improve engine power delivery to the ground while reducing stress on the engine and transmission during demanding use. Constructed with a 7.50-inch ring gear diameter and 10 ring gear bolts, this set also includes a 23-spline pinion. USA Standard Gear utilizes state-of-the-art software and advanced manufacturing technologies to produce a gear set that is both robust and straightforward to install and set up. The product is available for front and rear axle applications. Installation of new gears generally requires common hand tools, a hydraulic press, and a dial indicator for correct setup. It is recommended to purchase a master overhaul kit, which typically includes new bearings, seals, shims, and a pinion crush sleeve, to ensure reliable and quiet operation for years to come. USA Standard Gear provides a one-year warranty against manufacturer defects on their ring and pinion sets. These gears are considered a lower-cost alternative compared to other manufacturers, though they are not recommended for quiet-running vehicles.
