Revolution Gear & Axle 11-19 Ford 10.5in 37 Spline Rear 5.38 Ratio Ring & Pinion Set

This Revolution Gear & Axle ring and pinion set features a 5.38 gear ratio, designed for Ford 10.5-inch rear axles with 37-spline shafts. This specific ratio is a popular choice when upgrading to larger, heavier tires, as it effectively increases torque to the wheels. By changing the ratio, you're essentially telling the engine to spin more times for every single rotation of the tire, which helps compensate for the added rotational mass and diameter of bigger rubber.

The set is constructed from durable steel, ensuring it can handle the increased stress that comes with larger tires and potentially more demanding driving conditions. Revolution Gear & Axle is known for well-built drivetrain components, and this ring and pinion set is no exception. Proper installation is key for any gear change; ensure you follow the manufacturer's guidelines for setup, backlash, and break-in procedures to get the most out of this upgrade and ensure longevity.

When installing a new ring and pinion, it's crucial to have the correct setup tools and to pay close attention to the pattern of gear contact. This ensures the gears mesh properly and wear evenly. If you're unsure about the process, consulting a professional mechanic is always a good idea.
