Precision Built For GM Front Axle Applications

The Yukon YGGM9.25-488R Ring & Pinion Set is engineered specifically for GM 9.25" IFS front differentials found in heavy-duty trucks from 1988-2015. This reverse rotation gear set is designed for front axle use and features a 30 spline pinion paired with a 12-bolt ring gear for reliable load handling. The 4.88 ratio is well suited for trucks running larger tires, helping restore proper gearing while maintaining manageable cruising RPMs. Yukon machines each gear set to OEM-level specifications, ensuring proper fitment and consistent contact patterns during setup. An advanced gear tooth surface finish reduces friction and heat, improving durability and overall efficiency under stress. These gears are thoroughly tested to meet strict quality standards before leaving the factory. If installing into a Dodge 9.25" front differential with a factory carrier, a ring gear spacer is required to complete the installation.
