Dana Spicer 2108462 Differential Drive Pinion Gear
The Dana Spicer 2108462 Pinion Gear is a genuine heavy-duty differential drive pinion designed for select Dana Spicer off-highway axle applications. The pinion is a critical component of the axle’s final-drive gearing, transferring rotational power from the driveline into the differential ring gear so torque can be distributed through the axle shafts to the wheels. Dana parts suppliers specifically identify 2108462 as a genuine Spicer off-highway axle pinion.
Manufactured for high-load off-highway drivetrain service, the 2108462 is designed to operate under the substantial torque, shock loading, and continuous-duty conditions encountered in construction, material-handling, industrial, and specialty equipment. Precision-machined gear teeth help maintain proper contact with the mating ring gear, supporting smooth torque transfer, reduced gear noise, and dependable axle performance.

Designed for Off-Highway Axle Service
Within a drive axle, the pinion gear receives power from the driveshaft or axle input and meshes with the larger ring gear attached to the differential carrier. This gear reduction changes the direction of power flow and provides the torque multiplication required to drive heavy equipment.
Because ring-and-pinion tooth geometry, ratio, bearing setup, backlash, and contact pattern must be precisely matched, correct identification of the axle assembly is particularly important when replacing the 2108462. Some parts databases associate this number with a matched bevel gear set, while commercial Dana parts catalogs identify it specifically as the differential drive pinion. For that reason, the axle model and Dana bill-of-material or assembly number should be verified before ordering.
The Dana Spicer 2108462 Pinion Gear is an OE-quality replacement for compatible Dana Spicer off-highway differential assemblies, providing the dimensional accuracy, gear strength, and durability required for demanding final-drive applications.
