The Zumbrota Drivetrain YMS19428-OEM is a front pinion seal engineered specifically for GM 8.25" and 9.25" IFS differentials. Designed for '88 and newer GM vehicles, this seal ensures a precise fit and hassle-free installation. Manufactured to meet or exceed OEM standards, the YMS19428-OEM offers exceptional performance and durability.
