Detailed Description

The Melling VS-739R valve spring is engineered for engines that need a standard replacement spring with performance-oriented pressure characteristics. Its dual spring construction, corrosion-resistant steel material, and defined height and pressure specifications make it suitable for a broad range of GM applications, from street use to more demanding valvetrain setups. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible With Chevrolet Camaro, Chevrolet Corvette, Chevrolet C10, GMC Jimmy, and other listed GM models, the VS-739R supports engines that require the specified installed height and spring pressures. The part number VS-739R is also useful when matching an OE-style replacement to the correct spring specification.

What It Helps Address

• Weak or fatigued valve spring tension
• Valve float at higher engine speeds
• Incorrect spring pressure during engine rebuilds
• Wear-related loss of valvetrain control
