BCBC VS-1700 Engine Valve Spring

Overview

The Melling VS-1700 engine valve spring is a standard replacement spring built for stock applications and performance use. It is engineered with CrSiV wire and a single-spring design to deliver consistent valve control across a wide range of GM vehicles, including Cadillac, Chevrolet, Buick, and GMC applications.

Use the VS-1700 when you need a valve spring that matches the required installed height and pressure range for the application. This part number, VS-1700, also cross-references Monroe Shocks & Struts (e.g., 160-1700, 12647873) for the same application.

Key Features

• Standard replacement valve spring for stock and performance engine builds
• CrSiV material for spring strength and durability
• Single spring design for controlled valve operation
• Installed pressure of 59.0 and open pressure of 144.0
• Fits a broad range of GM applications, including Cadillac, Chevrolet, Buick, and GMC

Detailed Description

Melling designs the VS-1700 for street, OEM-style service, and performance use, with coverage that spans standard, mid-range, heavy-duty, and race-ready spring needs. The spring uses a single-spring layout and standard replacement grade, making it a practical choice for engines that require the specified installed height, coil bind height, and pressure characteristics. If you are servicing a Cadillac CT5, Chevrolet Camaro, or GMC Acadia, this valve spring provides the dimensional and pressure specifications needed for the application.

What It Helps Address

• Weak or fatigued valve spring tension
• Valve float at higher engine speeds
• Incorrect spring pressure for the specified build
• Loss of consistent valve control during operation

Installation Notes and Tips

Verify installed height, coil bind height, and spring pressure before installation. Confirm the cylinder head and valvetrain specifications match the required dimensions for the engine. This part is listed for stock applications across multiple Cadillac, Chevrolet, Buick, and GMC models, so application verification is important before assembly.

Quality Assurance

Melling offers valve springs across standard, heavy-duty, and race-ready categories, with designs that include single springs, dual springs, and beehive styles. The VS-1700 follows that product line approach with a standard replacement specification for the listed applications.
