Key Features

• Chrome silicon valve spring construction for consistent performance.
• Single spring design for standard replacement use.
• Hydraulic roller camshaft type specification.
• 71 lb installed pressure and 166 lb open pressure.
• Fits Ford F-150 and Ford Mustang applications listed below.

Detailed Description

The Melling VS-1618 is an engine valve spring intended for applications that call for a standard replacement spring with defined pressure and dimensional specs. Its chrome silicon material, 1.575-inch installed height, 1.04-inch coil bind height, and 1.102-inch spring open height provide the measurements needed to match the valvetrain setup correctly. This part number, VS-1618, is listed for 2015-2017 Ford F-150 and 2012-2017 Ford Mustang stock applications, making it a relevant choice when servicing those engines. The VS-1618 is also cross-referenced to CR3Z 6513-A and RV-3715 for the same application.

Common Uses

• Replacing a worn or weakened valve spring.
• Restoring proper valve control in a hydraulic roller setup.
• Addressing inconsistent spring pressure during engine service.
• Matching a standard replacement spring specification during rebuild work.

Installation Notes

Verify installed height, coil bind height, and spring pressure against the engine build before installation. Confirm the hydraulic roller camshaft specification and compare the spring dimensions to the original valvetrain requirements. Use the vehicle fitment list to confirm the correct Ford F-150 or Ford Mustang application before ordering.

Quality Assurance

Melling offers valve springs across standard, heavy-duty, and race-oriented applications, with multiple spring designs and pressure ranges available. The VS-1618 is part of that product line and is built as a standard replacement component for specified engine applications.
