DJ Rock IV3215A Engine Intake Valve

Engine Intake Valve for GM V8 Applications

The DJ Rock IV3215A is a premium engine intake valve built for precise airflow control in compatible GM applications. With a nitride-coated surface, 55 mm valve head diameter, 7.96 mm stem diameter, and 123.7 mm overall length, this intake valve is specified for direct-fit replacement where exact valvetrain dimensions matter.

Fits 2008-2020 Chevrolet Corvette, 2009-2015 Chevrolet Camaro, and 2009-2013 GMC Sierra 1500 applications with the listed intake-valve specifications. The IV3215A part number is also used across a wide range of Chevrolet, GMC, Cadillac, Pontiac, and Hummer vehicles.

Key Features

• Nitride-coated valve surface for added wear resistance and corrosion protection
• 55 mm valve head diameter for application-specific intake-valve fitment
• 7.96 mm stem diameter and 123.7 mm overall length
• Single lock groove design
• Premium-grade replacement for engine valve train service
• DJ Rock IV3215A intake valve for direct-fit replacement use

Detailed Description

This engine intake valve is engineered to open at the correct camshaft interval so the air-fuel charge enters the combustion chamber with the proper timing and volume. The nitride coating helps reduce friction and improve surface durability under heat and mechanical load, while the alloy construction is selected for high-temperature engine environments. For technicians and rebuilders working on Chevrolet Silverado 2500 HD, GMC Savana 3500, or Cadillac Escalade applications, the IV3215A provides the dimensional accuracy needed for valvetrain service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Uses

• Replacing a worn or heat-damaged intake valve
• Restoring compression loss caused by valve sealing issues
• Addressing rough idle, misfire, or poor cylinder breathing
• Supporting engine rebuilds on GM V8 platforms
• Correcting valvetrain wear in high-mileage engines

Installation Notes and Tips

Verify valve head diameter, stem diameter, overall length, and groove configuration before installation. Match the intake-valve application to the exact vehicle year and engine specification, especially on Chevrolet Express 2500, GMC Sierra 3500 HD, and Pontiac G8 listings where notes vary by configuration. Professional cylinder head service, including inspection of guides, seals, and valve seats, is recommended during installation.

Quality Assurance

DJ Rock IV3215A is manufactured to meet or exceed OEM quality standards and is built as a direct-fit replacement intake valve for demanding engine service.
