FAG SS3165 Manual Transmission Seal - Rear

Manual Transmission Seal for Borg-Warner Applications

FAG SS3165 is a manual transmission seal built for specific rear-position applications that require a 2.250 inch shaft and precise sealing dimensions. It uses a nitrile sealing material with a metal shell, spring, and auxiliary lip to help maintain a tight seal at the transmission output area.

Compatible With 1963-1968 Chevrolet and GMC rear transmission applications listed below, including Chevrolet C10 Suburban, C20 Suburban, K10 Suburban, K20 Suburban, and GMC G1000 Series and G1500 models. FAG SS3165 is specified for Borg-Warner, New Process, and Muncie transmission applications where the listed dimensions match.

Detailed Description

FAG SS3165 is a transmission seal engineered to match demanding vehicle-specific sealing requirements. The nitrile sealing element, spring-loaded design, and auxiliary lip help maintain contact at the sealing surface, while the metal shell supports proper fit in the bore. With a 2.997 inch bore diameter and 3.001 inch outside diameter, this seal is built around exact dimensional control for the listed Chevrolet and GMC manual transmission applications. This part number, SS3165, is used in rear-position Borg-Warner, New Process, and Muncie transmission setups where the 2.250 inch shaft specification is called out.

This part cross-references Gates 22340 and National 471341 for the same application.

What It Helps Address

• Transmission fluid leakage at the rear seal area
• Contamination from dirt, dust, and moisture entering the seal zone
• Grease or lubricant loss around the shaft interface
• Wear-related sealing issues in older manual transmission assemblies
• Fitment problems when the bore and shaft dimensions must match exactly

Installation Notes and Tips

Verify the transmission type, rear position, bore diameter, outside diameter, seal width, and 2.250 inch shaft specification before installation. Clean the sealing surface and housing thoroughly, and inspect the shaft for wear, scoring, or corrosion that could affect seal life. Confirm the application against the vehicle listing for Chevrolet C10 Suburban, C20 Suburban, K10 Suburban, K20 Suburban, GMC G1000 Series, and GMC G1500 models before assembly.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The sealing construction is selected to protect wheel-end and transmission components from contamination while helping retain lubricant over the service life of the bearing or seal assembly.
