Key Features

• Corrosion-resistant steel construction for dependable service in engine hardware applications
• Single spring design with standard replacement grade
• Open pressure rated at 205.0 for controlled valve operation
• Fits applications with a 1.22 coil bind height and 1.3 spring open height
• Inside diameter of 0.995 and outside diameter of 1.395 for specified fitment

Detailed Description

The Melling VS-830 valve spring is part of the Stock product line and is intended for engines that need a direct replacement spring with defined pressure and dimensional requirements. Melling offers a broad range of valve spring designs, including standard, dual, damped, and beehive styles, and this VS-830 follows that engineering approach with a single-spring, standard replacement configuration. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. It is listed for a wide set of Ford, Lincoln, Mercury, and Chrysler applications, including Ford F-150, Ford Bronco, and Chrysler 300 fitments, with notes that specify camshaft and rocker-arm requirements. The VS-830 part number is useful when matching the correct spring to the engine build and valve train setup.

What It Is Used For

• Replacing a worn or weakened valve spring in a stock engine build
• Restoring valve control when spring pressure has dropped
• Matching a specified camshaft or rocker-arm setup
• Addressing valve train instability caused by incorrect spring dimensions
• Supporting intake or exhaust valve service on listed applications

Installation Notes and Tips

Verify the application notes before installation, especially camshaft requirements such as SYB-21, SYB-25, or SYB-26, and exclusions such as MTF-2 where listed. Confirm coil bind height, open height, and spring pressure against the engine specification before assembly. The VS-830 is used across multiple Ford, Lincoln, Mercury, and Chrysler fitments, so match the part number and notes carefully to the exact engine configuration.
