Federal Mogul FPVS356 Engine Valve Spring

The Federal Mogul FPVS356 is a precision-engineered engine valve spring designed to maintain consistent valve train control and reliable sealing performance. Federal-Mogul, operating under its trusted Sealed Power brand, has manufactured engine components to original equipment standards for decades, making this valve spring a dependable choice for engine repair and rebuilding applications.

Valve springs are a critical component of the valve train assembly, providing the tension needed to keep intake and exhaust valves properly seated during combustion cycles. A worn or fatigued valve spring can lead to valve float, loss of compression, rough idle, and reduced engine performance — making timely replacement essential.

Key Features:

• Manufactured to meet or exceed original equipment specifications
• Engineered for consistent spring pressure and fatigue resistance
• Precision wound for uniform coil spacing and reliable valve seating
• Produced by Federal-Mogul / Sealed Power, a trusted OEM-level engine parts supplier
• Suitable for engine rebuild and replacement applications

The Federal Mogul FPVS356 valve spring is sold individually. Always verify correct spring specifications — including free length, installed height, and seat pressure — against your engine's service manual before installation.
