BCBC VS-1642 Engine Valve Spring

Engine Valve Spring Overview

Melling VS-1642 is a standard replacement engine valve spring built for stock and performance applications that use a hydraulic roller camshaft. It is specified for a wide range of Chrysler, Dodge, Jeep, and Ram applications, including the Dodge Charger, Dodge Challenger, and Ram 1500.

With chrome silicon vanadium construction and a single-spring design, this valve spring is engineered around controlled seat and open pressures for consistent valvetrain operation. The VS-1642 is a direct-fit style option for buyers looking for a replacement spring with defined installed height and pressure specifications.

Key Features

• Chrome silicon vanadium material for valvetrain spring service
• Single spring design with standard replacement grade
• Hydraulic roller camshaft application
• Installed pressure: 117.0
• Open pressure: 332.0
• Fits a broad range of Chrysler, Dodge, Jeep, and Ram applications

Detailed Description

The Melling VS-1642 valve spring is designed for engines that require a standard replacement spring with specific pressure and height values. Its 1.988 installed height, 1.466 spring open height, and 1.429 coil bind height provide the dimensional reference needed when matching valvetrain components. The 0.65 inside diameter and 1.299 outside diameter further define the spring for proper fitment in supported engine builds. This part cross-references Monroe Shocks & Struts (e.g., 32-5024, 160-1642SSA) for the same application.

Compatible with stock-use applications across the Dodge Durango, Ram 2500, Ram 3500, Jeep Grand Cherokee L, Ram 1500, Ram 1500 Classic, Ram 4500, Ram 5500, Chrysler 300, Dodge Challenger, Dodge Charger, Jeep Grand Cherokee, Jeep Wagoneer, Dodge Ram 1500, Dodge Ram 2500, Dodge Ram 3500, and Jeep Commander. The VS-1642 part number is also useful when matching replacement specifications against existing valvetrain service records.

What It Is Used For

• Replacing a worn or weakened valve spring
• Restoring correct seat and open pressure in the valvetrain
• Addressing valve control issues caused by spring fatigue
• Matching a hydraulic roller camshaft spring specification
• Supporting stock engine service on listed applications

Installation Notes and Tips

Verify installed height, coil bind clearance, and spring pressure before installation. Confirm the engine uses a hydraulic roller camshaft and compare the spring dimensions to the original specification. Use the vehicle fitment list to confirm the correct application for your Chrysler, Dodge, Jeep, or Ram engine build. The VS-1642 part number should be matched carefully during service work to avoid valvetrain mismatch.

Quality Assurance

Melling offers valve springs across standard, heavy-duty, and race-ready categories, with multiple wire sizes, materials, and spring pressure ranges available. VS-1642 follows that product line approach with a standard replacement specification for supported applications.
