This Melling Performance push rod, part number 500704, is built for engine valvetrain service where material strength and geometry matter. It uses chrome moly steel construction and rounded tips to support consistent contact in compatible Chevrolet, GMC, Cadillac, Pontiac, Buick, Hummer, Saab, Isuzu, and Avanti applications.

Key features

• Chrome moly steel construction for performance-oriented valvetrain use
• Rounded top and bottom tips for stable contact at both ends
• 0.315 in. diameter for the specified application
• 7.400 in. length for direct application matching
• Made in the USA

Detailed description

Melling part number 500704 is a performance-grade engine push rod intended for applications that require a chrome moly steel valvetrain component. The design follows strict manufacturing specifications and is offered for a wide range of GM-based engines found in Chevrolet Silverado 1500, Chevrolet Camaro, and GMC Sierra 2500 HD applications, along with other listed vehicles. Melling also notes that new push rods should be installed during service to maintain proper valve train geometry and performance.

This part cross-references Monroe Shocks & Struts (e.g., MT7400-080) for the same application.

What it is used for

• Replacing a worn or bent push rod in the valvetrain
• Restoring correct valve train geometry after engine service
• Addressing valvetrain noise caused by damaged push rod components
• Supporting consistent valve actuation in performance engine builds
• Matching the specified length and tip design for listed applications

Installation notes and tips

Verify push rod length, diameter, and tip style against the engine specification before installation. Inspect related valvetrain components for wear, and replace any damaged parts that could affect geometry or contact pattern. Confirm fitment by vehicle, engine, and application notes before assembly. Part number 500704 should be matched to the exact listed application.

Quality assurance

Melling manufactures this push rod in the USA and builds it to stringent specifications using quality materials and controlled production processes. The Performance line includes chrome moly push rods for higher-demand engine applications, and Melling recommends installing new push rods during service to help maintain proper valvetrain geometry.
