BCBC VS-1130 Engine Valve Spring

Engine Valve Spring for Ford and Mercury Applications

Melling VS-1130 is a standard replacement engine valve spring built for stock-style and performance use. It is made in the USA and specified for a wide range of Ford and Mercury applications from 1964-1969, including Mustang, Falcon, Cougar, and Bronco fitments.

This valve spring uses corrosion-resistant steel and a single-spring design with defined installed and open pressure values for consistent valvetrain control. The VS-1130 part number is also referenced for several stock applications and select combinations that call for the SYB-25 camshaft.

Detailed Description

VS-1130 is part of Melling’s Stock line, which covers standard, mid-range, heavy-duty, and race-ready valve spring applications. This spring is intended for buyers who need a direct replacement-style valve spring with published pressure and height specifications for engine assembly and service work. The VS-1130 part number appears across multiple Ford and Mercury engine applications, including 1964-1969 Ford Mustang, 1966-1968 Ford Bronco, and 1967 Mercury Cougar listings.

This part cross-references Monroe Shocks & Struts (e.g., 32-902, 32-906) for the same application.

What It Helps Address

• Weak or fatigued valve spring tension
• Incorrect installed height during valvetrain setup
• Loss of valve control at operating speed
• Spring bind concerns in matched engine builds
• Replacement needs for stock-style Ford and Mercury engines

Installation Notes and Tips

Verify installed height, coil bind clearance, and spring pressure before final assembly. Match the spring to the camshaft and valvetrain specifications listed for the application, especially where the notes call for the SYB-25 camshaft or a specific production change. Confirm the engine configuration before ordering, since the fitment list includes multiple Ford and Mercury models with year-specific notes.
