Fel-Pro SS13401 is an engine valve stem oil seal set for classic domestic applications using compatible Ford, Mercury, Edsel, AC, and Shelby engines from the late 1950s through the 1970s. The deflector style seals help meter oil at the valve stems, a common fix for worn seals that can contribute to oil consumption and blue exhaust smoke. Application-specific engineering, polyacrylate and rubber construction, and the included installation tool make this a practical service part for vintage trucks, muscle cars, wagons, and performance platforms.

Fel-Pro SS13401 Features:

• Deflector, also called umbrella style, seal design helps control oil around the valve stem as it moves through the valve guide.
• Sold as a 16-piece valve stem oil seal set for a complete service on supported engine applications.
• Polyacrylate and rubber materials are selected for the heat cycling and oil exposure common in classic engine repair work.
• Application-specific design supports direct replacement service with no machine work required according to the product data.
• Fits a broad range of vintage platforms, including Ford F-100, F-250, F-350, Mustang, Fairlane, Galaxie 500, Thunderbird, Ranchero, Mercury Cougar, Comet, Cyclone, Monterey, Edsel Ranger, Shelby Cobra, AC 427, AC 428, and AC Shelby Cobra applications.

Includes:

• 16 deflector style valve stem oil seals
• Installation tool to help protect the seal lip during installation

Use this set when servicing worn or damaged valve stem seals during cylinder head work or top-end repair. It is especially relevant for classic Ford and Mercury trucks, wagons, car-based pickups, and performance cars where oil control at the valve guide is part of restoring proper engine operation.

Coverage spans select 1957-1977 Ford, Mercury, Edsel, AC, and Shelby applications. Verify engine and vehicle fitment before ordering, especially on classic models that may have had engine swaps or cylinder head changes over time.
