BCBC VS-730 Engine Valve Spring

Engine Valve Spring Overview

Melling VS-730 is a standard replacement engine valve spring built for a wide range of Cadillac applications. It uses corrosion-resistant steel and a single-spring design to deliver consistent valve control for stock and performance-oriented builds.

Key Features

• Corrosion-resistant steel construction for dependable service life.
• Single spring design for standard replacement use.
• Installed height of 1.94 in. and installed pressure of 63.0.
• Open pressure of 160.0 with a coil bind height of 1.394 in.
• Fits Cadillac engine applications across multiple model lines.

Detailed Description

The Melling VS-730 valve spring is engineered for applications that need controlled valve motion and stable spring pressure. Its dimensions include a 0.872 in. inside diameter, 1.212 in. outside diameter, and a spring open height of 1.496 in., making it a direct-fit option for engines that match these specifications. This part cross-references Monroe Shocks & Struts (e.g., 32-619, 050-619) for the same application. The VS-730 is a practical choice for Cadillac DeVille, Fleetwood, and Commercial Chassis applications where a standard replacement spring is required.

What It Is Used For

• Restoring valve spring tension in worn engine assemblies.
• Replacing fatigued springs that no longer hold consistent pressure.
• Supporting stable valve operation in stock rebuilds.
• Addressing spring-related valvetrain noise or irregular motion.

Installation Notes and Tips

Verify installed height, coil bind height, and pressure requirements before installation. Match the spring to the cylinder head and valvetrain specifications for the engine being serviced. Confirm application details for Cadillac DeVille, Fleetwood, and related models before ordering. The VS-730 should be installed only where the listed dimensions and spring type align with the engine build.

Quality Assurance

Melling offers valve springs across standard, mid-range, heavy-duty, and race-ready applications, with designs that include standard, dual, and beehive styles. VS-730 is part of the Stock line and is built as a standard replacement component.
