Engine Valve Spring for Stock Applications

The Melling VS-310 engine valve spring is a standard replacement part built for stock applications across a wide range of Pontiac, Buick, and Oldsmobile engines. It uses corrosion-resistant steel and a single-spring design to match the specified installed height and pressure requirements.

Corrosion-resistant steel construction for dependable valve train service.
Single-spring design for standard replacement use.
Installed height of 1.56 in. with 31.0 lb installed pressure.
Open pressure of 102.0 lb at 1.114 in. spring open height.
Fits stock applications listed for Pontiac, Buick, and Oldsmobile engines.

Detailed Description

The Melling VS-310 is a standard replacement engine valve spring intended for stock valve train setups that require the listed height and pressure specifications. It is part of Melling’s Stock line and is engineered with corrosion-resistant steel, a 0.768 in. inside diameter, and a 1.065 in. outside diameter to meet the dimensional needs of the specified applications. This part cross-references Monroe Shocks & Struts (e.g., 32-813, 050-813) for the same application. Fits 1967-1979 Pontiac Firebird, inner, and fits 1979-1980 Buick Century, inner, when used with the specified camshaft notes. The VS-310 is also listed for other Pontiac, Buick, and Oldsmobile stock applications, including 1955-1985 coverage in the fitment table.

What It Is Used For

Replacing a worn or weak valve spring in a stock engine build.
Restoring valve control when spring pressure has dropped.
Addressing valve train instability caused by fatigue or age.
Matching a spring to the listed installed height and pressure requirements.
Supporting stock camshaft applications noted in the fitment data.

Installation Notes and Tips

Verify installed height, coil bind clearance, and spring pressure before installation. Review the fitment notes carefully, since some applications require a specific camshaft or exclude Ram Air engines and manual transmission configurations. Confirm the engine application and valve train specifications for your Pontiac, Buick, or Oldsmobile before ordering the VS-310.

Quality Assurance

Melling offers a range of valve springs for standard, heavy-duty, and race-oriented use, and the VS-310 is part of its standard replacement Stock line.

This part fits 154 vehicles

Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
