Rear Inner Differential Pinion Seal for Heavy-Duty GM Axles

The InMotion WS2081 is a rear inner differential pinion seal built for select Chevrolet and GMC trucks, vans, and SUVs with 10.5-inch ring gear applications and related Spicer axle configurations. It uses nitrile sealing material, a SAE 1008 spring, and a SAE 1070 seal case to help maintain a tight seal around the pinion area.

For Chevrolet C2500, GMC K3500, and other rear inner applications, this seal is sized for a precise housing and shaft fit. InMotion WS2081 is a direct replacement option for servicing leaks at the differential pinion seal location.

Key Features

Nitrile sealing material for oil resistance and dependable sealing performance
SAE 1008 spring material for consistent sealing tension
SAE 1070 seal case material for structural support
Inside diameter: 2.82 in. / 71.7 mm
Outside diameter: 3.95 in. / 100.2 mm
Width: 0.495 in. / 12.6 mm
Shaft diameter: 2.843 in. / 72.2 mm
Housing bore: 3.939 in. / 100.1 mm
External markings: 12003

Detailed Description

Built for rear inner differential service, InMotion WS2081 is engineered to create a secure barrier against debris and moisture at the pinion seal location. The nitrile sealing lip is paired with a spring-loaded design to maintain contact pressure, while the metal case helps the seal retain its shape during operation. This makes it a practical choice for maintaining differential integrity in trucks and vans that see towing, hauling, or daily driving.

This part cross-references common OE-style applications for the same service position. Compatible vehicle coverage includes Chevrolet C2500, K2500, C3500, Express 2500, Express 3500, Silverado 2500, and GMC C2500, K2500, K3500, Savana 2500, Savana 3500, Sierra 2500, and Yukon XL 2500 in rear inner positions where the listed axle notes apply. Part number WS2081 is also a useful reference when sourcing a rear inner differential pinion seal for 10.5-inch ring gear and select Spicer axle setups.

What It Helps Address

Differential fluid seepage at the pinion seal area
Contamination from road debris and moisture entering the axle housing
Seal wear from age, heat, and drivetrain use
Loss of sealing tension around the pinion shaft
Service needs on rear inner axle seal replacement jobs

Installation Notes and Tips

Verify axle type, ring gear size, and housing bore before installation. This seal is listed for rear inner positions only, with many applications requiring a 10.5-inch ring gear or specific Spicer axle notes. Inspect the pinion yoke and sealing surface for wear or scoring before installing WS2081, and confirm the shaft diameter and housing bore match the published dimensions.

Quality Assurance

InMotion WS2081 is manufactured with nitrile, SAE 1008 spring material, and a SAE 1070 seal case to support consistent sealing performance in differential service. The part is specified with published dimensions and fitment data for accurate application matching on Chevrolet and GMC rear inner axle positions.
