Yukon Gear High Performance Gear Set Chrysler Rear 9.25in ZF Axles in 3.21 Ratio

When you're looking to change your Ram 1500's final drive ratio, this Yukon Gear & Axle high-performance ring and pinion gear set is what you'll need. This set is designed for the Chrysler 9.25-inch ZF rear axle found in 2011 through 2019 Ram 1500 trucks, and it comes in a 3.21 ratio. This specific ratio is often chosen to help compensate for larger tires or to improve fuel economy on the highway.

Yukon engineers put a lot of thought into these gear sets. They use high-grade steel for both the ring and pinion gears, and the tooth surface finish is designed to cut down on friction and heat. This means the gears will run cooler and last longer. The fitment is designed to OEM specifications, so you can expect it to install correctly in your 9.25-inch ZF axle. Yukon also backs these sets with a lifetime Y.E.S. Plan, which is a comprehensive, no-questions-asked protection plan for as long as you own your vehicle.

Installing a new ring and pinion gear set is a job that requires precision and specific tools. It's highly recommended to consult the manufacturer's installation instructions and consider using a professional installation kit, which typically includes bearings, seals, and installation hardware. This ensures everything is set up correctly for optimal performance and longevity.
