Detailed Description

FAG SS2377 is an engine camshaft seal engineered to match vehicle-specific dimensions and sealing requirements. The nitrile sealing surface is paired with a spring-loaded rubber design and auxiliary lip to help control oil at the camshaft interface while supporting long-term sealing performance. The listed dimensions are 1.89 inches bore diameter, 1.899 inches outside diameter, and 1.339 inches width, making fitment verification straightforward during service.

Compatible With 2011-2019 Nissan Versa, 2009-2010 Subaru Impreza, 2009-2010 Subaru Legacy, 2009-2010 Subaru Outback, 2000-2005 Mazda Miata, and many additional applications listed in the fitment data. It also covers vehicles such as the Nissan Frontier, Nissan Xterra, Mazda Protege, Kia Sportage, Ford Probe, and Mercury Villager where the specified engine configuration calls for this seal.

What It Helps Address

• Oil seepage at the camshaft seal area
• Contamination entering the sealing interface
• Loss of lubrication around the camshaft end
• Seal wear from age, heat, and mileage
• Service replacement for leaking front engine sealing points

Installation Notes and Tips

Confirm bore diameter, outside diameter, and width before installation. Match the seal to the exact year, make, model, engine, and position shown in the fitment data, especially on Subaru, Nissan, Mazda Miata, and Nissan Frontier applications where engine configuration matters. Inspect the camshaft surface for scoring or wear before installing the new seal, and clean the sealing bore thoroughly so the lip seats evenly.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain FAG quality standards. The SS2377 is built for demanding sealing applications where contamination control and grease or oil retention are critical to bearing and engine component life.
