PAI 94470 Side Gear

PAI 94470 Differential Side Gear – 18 Tooth, 41 Spline (Replacement for Dana / Spicer 110527)

The PAI 94470 Differential Side Gear is a premium aftermarket replacement designed as a direct interchange for Dana / Spicer 110527. Engineered for heavy-duty commercial truck and vocational axle applications, the 94470 features 18 external gear teeth and 41 internal involute splines, providing reliable torque transfer, precise gear engagement, and long service life in demanding operating environments.

Manufactured to meet or exceed OEM performance standards, the PAI 94470 is intended for use in a wide range of Dana Spicer single- and double-reduction drive axles commonly found in Class 6, 7, and 8 trucks, construction equipment, refuse vehicles, logging trucks, mixers, and other severe-service applications. The gear is manufactured from heat-treated alloy steel and precision machined to ensure accurate fitment and dependable operation throughout the life of the differential.

As one of the primary torque-transmitting components inside the differential carrier, the side gear splines directly to the axle shaft and meshes with the differential spider (pinion) gears. This allows engine torque to be transferred efficiently to the wheels while permitting each wheel to rotate at different speeds during cornering.
