Detailed Fitment and Application

VS-330 is built as a standard replacement spring for stock and mild performance valve train setups. The listed dimensions and pressure ratings help match the spring to the correct installed height and operating range, while the dual-spring layout supports stable valve control in compatible Chevrolet and GMC engines. This part cross-references Chevrolet OEM number 3856860 and Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Address

• Weak or inconsistent valve spring pressure
• Valve float at higher engine speeds
• Incorrect spring height during rebuilds
• Worn or fatigued original valve springs
• Replacement needs for stock-style engine service

Installation Notes and Tips

Verify installed height, coil bind clearance, and spring pressure before assembly. For 1970 Chevrolet Camaro applications, use with CCS-20 camshaft where specified. Some 1968-1969 Chevrolet Chevelle, Nova, and Chevy II applications exclude high-performance and special high-performance engines, so confirm engine specifications before installation.
