Detailed Description

The Melling VS-739 valve spring is engineered for engine builds that need a standard replacement spring with defined pressure and height specifications. Its dual spring construction and corrosion resistant steel material support consistent valve control in street, OEM-style, and performance-oriented applications. The VS-739 part number appears across a broad fitment range that includes Chevrolet Camaro, Chevrolet Corvette, GMC Jimmy, and many other Chevrolet and GMC models with stock 7.00 coil notes.

Melling’s spring lineup covers standard, mid-range, heavy-duty, and race-ready needs, and this Stock brand line reflects that broad replacement focus. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Weak or fatigued valve spring tension
• Valve float at higher engine speeds
• Inconsistent valve control during operation
• Spring replacement during cylinder head service
• Restoration of stock-style spring specifications

Installation Notes and Tips

Verify installed height, coil bind clearance, and spring pressure before installation. Confirm that the application matches the listed stock 7.00 coil notes and the engine’s valve train requirements. Because fitment spans many Chevrolet and GMC platforms, compare the spring dimensions and pressure ratings to the original specification before assembly.

Quality Assurance

Melling supplies valve springs for standard replacement and performance use across street, OEM, drag race, and circle track applications. The VS-739 is built to published dimensional and pressure specifications for consistent selection during engine service and rebuild work.
