Federal Mogul SS72525 Valve Stem Seal Set - 16 Piece Umbrella Style

The Federal Mogul SS72525 valve stem seal set provides a complete sealing solution for small block Chevrolet 5.0L (305ci) and 5.7L (350ci) Gen I engines. This comprehensive set includes 16 umbrella-style (deflector) valve stem seals engineered to control oil lubrication as valve stems move through the valve guides, preventing excessive oil consumption while ensuring proper valve train lubrication.

Key Features:

• Application-specific design with umbrella-style deflector seals that move with the valve to shield the guide from excess oil
• Premium materials validated for fit, form, and function to meet or exceed OE specifications
• Engineered by Fel-Pro specialists using rigorous research, development, and testing protocols
• Includes installation tool to protect the inner seal lip from damage during installation
• No machine work required for installation

Valve stem seals play a critical role in engine performance by precisely metering oil flow to the valve guides. When seals become worn or degraded from heat exposure, symptoms include blue-white exhaust smoke, excessive oil consumption, and carbon buildup on valves. This Fel-Pro replacement set restores proper sealing to maintain optimal engine efficiency and reduce oil consumption.
