Revolution Gear & Axle 11-25 Ford F-150 9.75in 31 Spline Rear 4.56 Ratio Ring & Pinion Set

This Revolution Gear & Axle ring and pinion set features a 4.56 gear ratio, designed for Ford 9.75-inch rear axles with 31-spline configurations. Choosing the right gear ratio is crucial for optimizing your vehicle's performance, especially if you've modified your truck with larger tires or plan to use it for towing heavy loads. A lower numerical ratio like 4.56 generally means your engine will turn more RPMs at a given road speed, which translates to improved acceleration and better pulling power, making it a popular choice for trucks that see regular work or off-road use.

Crafted from durable steel, this set is built to handle the stresses of daily driving and demanding tasks. The 31-spline count ensures a strong connection to your axle shafts, and the 9.75-inch ring gear size indicates it's built for the robust rear differentials found in many Ford F-150 models. Proper installation by a qualified technician is recommended to ensure the gears mesh correctly, which is key for quiet operation and long-term durability.

When upgrading your ring and pinion, it's important to consider that changing the gear ratio will affect your speedometer readings and potentially your fuel economy. You may need to recalibrate your speedometer to ensure accuracy. This set is a solid option for F-150 owners looking to fine-tune their truck's drivetrain for specific needs.
