When you're looking to change the gear ratio in your 2011-2019 Ram 1500's 9.25-inch ZF rear axle, this ring and pinion gear set from Yukon Gear & Axle is a solid option. This set includes the ring gear and the pinion gear, which work together to change how your truck's wheels turn relative to the driveshaft. The 3.90 ratio is a popular choice for those who have added larger tires or increased horsepower, helping to bring your truck's performance back into an optimal range.

Yukon Gear & Axle uses high-grade steel for both the ring and pinion gears, and they've designed the gear tooth surface finish to reduce friction and heat buildup. This attention to detail in materials and design helps ensure the gears meet exacting specifications and quality standards. The fitment is designed to OEM specifications, meaning it should install cleanly into your Ram's rear differential. This set features a 12-bolt design and the specific 3.90 ratio you're looking for.

Installing a new ring and pinion set is a job that requires precision and specific tools, often involving setting backlash and gear pattern. It's recommended to consult the manufacturer's installation instructions or a professional mechanic to ensure proper setup. Yukon Gear & Axle also backs this gear set with their Y.E.S. Plan, a lifetime, no-questions-asked protection plan for as long as you own your vehicle.
