Detailed Description

The Melling VS-510 valve spring is part of the Stock line and is engineered for applications that call for a standard replacement spring rather than a race-specific setup. Its corrosion resistant steel construction, single-spring layout, and specified pressure range make it suitable for maintaining valve control in engines that rely on original-style spring dimensions. This part number, VS-510, is listed across multiple Buick and Pontiac intake applications, along with several Jeep engine applications, making it a useful reference when matching spring specifications to the correct build. The VS-510 is also cross-referenced to Monroe Shocks & Struts part numbers 172286 and 182286 for the same application.
