Detailed description

This Melling Performance camshaft is designed to deliver fair idle quality while improving torque and horsepower in the low to mid range. The hydraulic roller design, 1.5 rocker ratio, and moderate duration profile make it a practical choice for drivers building a performance-oriented Chevrolet Silverado, Tahoe, or GMC Yukon engine without moving to an extreme race-only profile. Part number 22280 is also listed for Chevrolet Express, Savana, Suburban, and related GM truck and van applications.

The camshaft’s advertised duration and valve lift figures indicate a profile that can support stronger airflow and throttle response while remaining usable with stock or modified engine combinations. Melling 22280 is part of the brand’s Performance line, which covers street, RV, strip, and circle track camshaft applications.

What it is used for

• Restoring or upgrading camshaft performance in a worn engine
• Improving low- to mid-range torque output
• Addressing weak throttle response from a mild factory cam profile
• Supporting a performance build with a hydraulic roller valvetrain
• Replacing a camshaft for Chevrolet and GMC truck or van applications

Installation notes and tips

Verify engine compatibility, valvetrain setup, and computer-control requirements before installation. Fitment notes indicate this camshaft may not be computer compatible in some applications. Confirm rocker arm ratio, lifter type, and supporting components before assembly. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
