Yukon builds these gears using premium high-strength steel and advanced heat-treating methods, so you’re getting parts that are as tough as they are precise. The quiet, smooth operation is a bonus you’ll notice the moment you hit the road. It’s the kind of upgrade that doesn’t just fix a problem, it transforms how your truck feels behind the wheel. And with Yukon’s lifetime Y.E.S. Plan backing you up, you’ve got confidence for every mile ahead.

Built For GM Front Axles With Proven Precision

The Yukon YGGM9.25-456R Ring & Pinion Set is specifically designed for GM 9.25" IFS front differentials used in 2500HD and 3500HD trucks from 1988-2015. It features a reverse rotation design tailored for front axle applications and includes a 30 spline pinion with a 12-bolt ring gear, ensuring solid engagement under load. The 4.56 gear ratio strikes a strong middle ground for trucks running larger tires or carrying heavier setups while still allowing for respectable cruising RPMs. Yukon manufactures this set to tight OEM-level tolerances using high-grade steel and advanced surface finishing, helping reduce both heat and friction during operation. These gears are tested to handle high-stress use without sacrificing smoothness or reliability. If you’re installing into a Dodge 9.25" front differential with a factory carrier, you’ll need a ring gear spacer to complete the setup, part number MRG925A. With a strong balance of performance and durability, this set is an ideal front-end solution for serious builds.
