Optimized For Balanced Performance In GM Front Axles

The Yukon YGGM9.25-373R Ring & Pinion Set is designed specifically for GM 9.25" IFS front differentials found in Silverado and Sierra 2500HD and 3500HD models from 1988-2015. Featuring a reverse rotation configuration made for front axle applications, it includes a 30 spline pinion and 12-bolt ring gear built for strength and long-lasting reliability. The 3.73 ratio offers a versatile gear range that works well in trucks used for mixed driving, combining solid low-end torque with reasonable highway RPMs. Yukon’s advanced gear machining ensures consistent tooth contact and minimal noise during operation, even under load. The surface finish is engineered to reduce friction and heat, promoting longer gear life and smoother performance over time. All components are made to exact OEM specifications, helping ensure a proper fit with fewer installation complications. For those fitting this into a Dodge 9.25" front with a factory carrier, a ring gear spacer is required, part number MRG925A.
