Mud Cover Conversion Plate 5/16-18 Steel

The Mud Cover Conversion Plate 5/16-18 Steel from WEHRS MACHINE is a precision fastening adapter engineered for custom vehicle suspension and chassis modifications where threaded port standardization is critical. This component exists to bridge incompatible threaded mounting points, allowing builders to install aftermarket components—such as adjustable coilovers, air suspension fittings, brake lines, or chassis bracing—into OEM or existing holes without drilling new threads or compromising structural integrity. Whether you're upgrading a track car, restoring a classic, or fabricating a custom suspension geometry, this conversion plate ensures a solid mechanical foundation.

Machined from steel with a 5/16-18 thread specification, this plate delivers robust load-bearing capacity under suspension articulation and dynamic stress. The 5/16-18 thread pitch (18 threads per inch) is a standard automotive fastening size, widely used in modern EFI fuel systems, vacuum distribution, and suspension hard-plumbing applications. At only 0.105 lbs and measuring 5 x 0.95 x 6 inches, the compact geometry allows installation in tight engine bay or chassis cavities without fouling nearby components. Steel construction resists corrosion better than aluminum in wet environments and withstands repeated vibration cycles without thread stripping—essential when mounting components that experience lateral or longitudinal shock loads.

Serious enthusiasts and professional fabricators rely on WEHRS MACHINE conversion plates when assembling custom suspension kits, hydro-formed chassis, or vintage vehicle restorations that demand period-correct or non-standard port configurations. Installation requires careful alignment during fastening to ensure perpendicular seating and optimal thread engagement. This adapter is ideal for any build requiring reliable threaded conversion without sacrificing structural strength or aesthetic finish. Stock this essential component when undertaking suspension overhauls, engine swaps with non-standard mounting, or custom fuel and brake line routing on track cars and street rods.
