FAG SS2106 Manual Transmission Speedometer Pinion Seal

Manual Transmission Speedometer Seal for GM Trucks

The FAG SS2106 manual transmission speedometer pinion seal is built for older Chevrolet and GMC truck and van applications that need a precise seal at the transmission speedometer drive. With a metal seal design and nitrile sealing material, it helps maintain a tight barrier where the speedometer pinion enters the transmission housing. This FAG SS2106 seal is a direct-fit service part for a wide range of classic GM platforms.

Detailed Product Overview

FAG SS2106 is a manual transmission speedometer pinion seal engineered to match vehicle-specific dimensions for GM rear-wheel-drive and 4x4 applications. It is designed for use where the speedometer drive assembly passes through the transmission, helping retain lubricant and keep contaminants out of the sealing area. This part cross-references DENSO Auto Parts 4010 for the same application. Common fitment includes Chevrolet C10, K10, K5 Blazer, P30, and GMC Jimmy models across the 1970s and 1980s, making the SS2106 a practical replacement for restoration and maintenance work on classic Chevrolet and GMC trucks.

What This Seal Helps Address

• Transmission fluid seepage at the speedometer pinion opening
• Contamination from dirt, dust, and moisture around the seal area
• Wear-related leakage on older GM manual transmission housings
• Speedometer drive service on classic Chevrolet and GMC truck platforms
• Replacement needs during transmission maintenance or restoration

Installation Notes and Tips

Verify the transmission application and seal dimensions before installation. Clean the bore and surrounding housing surface thoroughly, and inspect the speedometer pinion area for wear or scoring that could affect sealing. For best results, install the seal squarely to avoid distortion of the metal case or nitrile lip. Confirm fitment against the vehicle listing before ordering, especially on Chevrolet Blazer, C1500, and GMC Jimmy applications.

Quality Assurance

FAG seals are manufactured to meet vehicle-specific specifications using materials selected for sealing performance and contamination control. The SS2106 follows the dimensional requirements listed for this application and is built for consistent service in compatible Chevrolet and GMC manual transmission setups.
