Detailed Description

FAG SS2823 is a transfer case output shaft seal designed around demanding sealing requirements for older Dodge, Chevrolet, and GMC 4x4 platforms. The seal uses nitrile sealing material with a metal and spring design to help retain lubricant at the output shaft while limiting contamination from road debris and moisture. Its listed dimensions make it a strong match for service work where correct bore diameter, outside diameter, and seal width are critical.

Fitment includes 1975-1977 Dodge D300, Ramcharger, W100, W200, and W300; 1977 Dodge W150; 1975 Chevrolet K10 and K20; 1973-1975 Chevrolet K10 Suburban, K20 Suburban, and Blazer; and 1973-1975 GMC Jimmy. For buyers searching by application, this is a practical choice for a 1975 Chevrolet K10 transfer case output shaft seal or a 1973-1975 GMC Jimmy front transfer case seal. Part number SS2823 is also referenced as FAG SS2823 in catalog listings.

What It Helps Address

• Transfer case fluid seepage at the output shaft
• Contamination entering the transfer case from dirt or moisture
• Loss of lubricant around the shaft seal area
• Wear-related sealing issues on older 4x4 driveline components
• Incorrect replacement sizing when restoring select Dodge, Chevrolet, or GMC transfer cases

Installation Notes and Tips

Verify shaft diameter, bore diameter, seal outside diameter, and seal width before installation. Clean the housing and shaft sealing surface thoroughly, and inspect for grooves, corrosion, or wear that could affect sealing performance. Proper alignment during installation is important to avoid damaging the spring-loaded lip. Confirm transfer case application details for your vehicle, especially on classic Dodge D300 and Ramcharger models and Chevrolet/GMC front transfer case applications.

Quality Assurance

FAG designs seals using materials selected to meet vehicle manufacturer specifications and quality standards. The SS2823 follows those dimensional and material requirements for select transfer case applications, supporting consistent sealing performance in service.
