  • Open pressure: 406.0
  • Installed height: 1.800 in. and coil bind height: 1.102 in.

Detailed Description

Melling 466564 is an engine valve spring designed for performance builds that require dual-spring control and consistent pressure characteristics. The chrome silicon construction and dual spring layout support valvetrain stability across a broad range of applications, including Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Camaro platforms that call for dual springs. This part number, 466564, is used in applications spanning street-driven trucks and SUVs through higher-output performance vehicles, making it a practical choice when matching spring specifications to the engine setup.

Melling’s Performance line covers standard, mid-range, heavy-duty, and race-ready spring options, with multiple wire sizes, materials, and spring pressures available. The 466564 follows that product-line approach by combining a dual spring design with defined installed and open pressure values for builders who need a specific valvetrain setup rather than a generic replacement.

What It Is Used For

  • Replacing worn valve springs that no longer hold consistent pressure
  • Addressing valve float in higher-rpm engine operation
  • Supporting performance camshaft and valvetrain combinations
  • Restoring proper spring control in dual-spring applications
  • Matching a specified installed height and pressure requirement

Installation Notes and Tips

Verify installed height, coil bind clearance, and spring pressure against the engine build before installation. This part fits applications listed with dual springs only, so confirm the valvetrain specification for your Chevrolet Silverado 2500 HD, GMC Sierra 3500 HD, or Chevrolet Camaro application before ordering. Part number 466564 should be matched to the cylinder head and camshaft requirements for the engine.

Quality Assurance

Melling’s Performance line is built around application-specific spring designs for street and competition use. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
