4.56 Ring and Pinion Gear Kit

The USA Standard Gear 8.6-Inch Rear Axle Ring and Pinion Gear Kit with Install Kit (ZGK2024) is engineered to transform your Silverado 1500 into a more capable towing and hauling vehicle. With a 4.56 gear ratio, this kit is designed to maximize performance, allowing for confident towing of heavy trailers and hauling of large payloads. Beyond enhanced towing, this lower gear ratio significantly improves acceleration, making it easier to merge onto highways and climb inclines. The kit also contributes to better fuel efficiency by reducing the engine's RPMs at cruising speeds, which in turn extends engine life and minimizes wear on critical components. USA Standard Gear utilizes advanced manufacturing techniques and premium, heat-treated materials for precision-machined gears, ensuring optimal performance and long-lasting durability even under heavy-duty use. Installation of this ring and pinion gear kit with the included master installation kit typically takes approximately one day. The kit contains all necessary components for a proper installation, including the ring gear, pinion gear, master installation kit, bearing installation kit, and shimming kit. The product comes with a one-year warranty. This USA Standard Gear kit is specifically designed to fit 1999-2008 Chevrolet Silverado 1500 models. It is compatible with vehicles featuring an 8.6-inch rear axle with a 10-bolt rear cover and 10-bolt ring gear. The kit includes bearings and seals required for installation.
