- Inside diameter: 1.875 in. (47.630 mm)
- Outside diameter: 3.165 in. (80.390 mm)
- Width / thickness: 0.562 in. (14.270 mm)

- Redicoat surface treatment
- Series 6000, Type 45
Product Details
National has supplied sealing solutions for more than 75 years, and the 6808N reflects that focus on dimensional accuracy and drivetrain sealing. This differential pinion seal is specified for rear outer positions on a range of classic trucks and performance vehicles, including Ford F-100, Ford F-250, Ford F-350, Jeep J20, Dodge Challenger, Dodge Charger, Chevrolet Blazer, Chevrolet C10 Suburban, Chevrolet K10 Suburban, and GMC Jimmy applications listed in the fitment data. The 6808N is also cross-referenced to Dorman - Autograde 29224 for the same application.
What It Helps Address
- Gear oil leakage at the differential pinion area
- Seepage around the pinion shaft seal surface
- Contamination from worn or hardened original seals
- Service issues on rear outer pinion seal locations
- Fitment concerns where 1.875-inch shaft and 3.165-inch OD dimensions are required
Installation Notes and Tips
Verify the shaft diameter, housing bore, width, and axle configuration before installation. This seal is listed for rear outer positions and specific axle setups such as Spicer 60, Spicer 60-35, Spicer 60.2, Spicer 70, and related ring gear applications shown in the fitment data. Inspect the pinion surface for wear or grooves before installing the new seal, and confirm the seal lip seats evenly in the housing.
Quality Assurance
National designs sealing components for modern and legacy vehicles with attention to material selection and dimensional control. The 6808N uses polyacrylate construction and Redicoat treatment to support consistent sealing performance in differential service.
