Complete your Gen 3 HEMI MDS delete with the Stanke Motorsports Billet Aluminum MDS Plugs Gen3MDS4. Designed specifically for Gen 3 HEMI applications, these plugs provide a purpose-built solution for blocking the MDS oil passages when eliminating the factory Multi-Displacement System. Each plug is machined from billet aluminum for a durable, professional installation that complements a properly planned HEMI performance build. Stanke also designed the plugs to be completely reusable, making them a valuable alternative for engines that may undergo future service, inspection, or additional modifications.

MDS elimination is common when upgrading the camshaft and valvetrain on applicable Gen 3 HEMI engines. The factory system uses oil pressure to control MDS-specific lifters and deactivate cylinders under certain operating conditions. When converting the engine to a non-MDS valvetrain configuration, the corresponding oil passages need to be properly addressed as part of the mechanical conversion. These Stanke plugs provide a dedicated component for completing that portion of the MDS delete.

One of the standout features of the Gen3MDS4 design is serviceability. Rather than installing a component that becomes difficult to remove during future engine work, Stanke designed these billet plugs specifically for straightforward removal using a 5/16-inch slide hammer. This can be particularly valuable for performance engines that may receive future camshaft changes, cylinder head upgrades, lifter service, or complete rebuilds.

Billet aluminum construction also makes these plugs a natural fit for performance-oriented engine builds. Stanke Motorsports specializes in machined engine components and specialty tools, with its Gen 3 HEMI catalog including rocker shaft stabilizers, collars, VVT components, oil system parts, and other engine-building hardware. The Gen3MDS4 plugs follow that same performance-focused approach with a simple component designed to solve a specific problem during HEMI assembly.

These MDS plugs are especially useful when completing a 5.7L or 6.4L Gen 3 HEMI camshaft and lifter conversion where the original MDS hardware is being removed. They pair naturally with non-MDS lifters, performance camshafts, upgraded valve springs, pushrods, and other supporting valvetrain components. Mechanical MDS removal also requires appropriate calibration changes, so custom tuning should be incorporated into the completed build.

For professional engine builders and DIY enthusiasts alike, the Stanke Motorsports Gen 3 HEMI Billet MDS Plugs provide a clean, reusable solution for an important step in the MDS delete process. Their billet construction, application-specific design, and easy-removal feature make them a smart addition to camshaft installations, valvetrain upgrades, and complete performance engine builds.
