Brass Freeze Plug Kit Chrysler 318/360

The PROFORM Brass Freeze Plug Kit for Chrysler 318/360 is a complete engine sealing solution designed for small block Mopar restoration, rebuild, and performance applications. This kit provides all necessary freeze plugs—the expansion plugs that seal coolant passages in the engine block—in a combination of steel and brass materials that deliver reliable corrosion resistance and proper thermal expansion control. Freeze plugs are critical wear items that prevent coolant leakage from the block's core casting holes, and a complete kit eliminates the need to source individual plugs from multiple suppliers.

The steel and brass composition of this kit is engineered for the specific thermal cycling demands of Chrysler 318 and 360 cubic inch engines. Brass plugs offer superior corrosion resistance in wet environments and provide excellent sealing characteristics under repeated heating and cooling cycles. The combination approach ensures compatibility across all freeze plug bore sizes in the small block Mopar engine block, whether you're rebuilding a factory engine or restoring a classic vehicle. This comprehensive kit approach saves time during engine assembly by providing matched plugs that work together as a system rather than requiring individual plug selection.

Technicians and engine builders working on Chrysler 318/360 restorations, long-block assemblies, or complete engine rebuilds rely on complete freeze plug kits to ensure proper coolant integrity from initial startup. Whether you're refreshing an original engine block, installing a performance crate motor, or performing preventive maintenance on a high-mileage block, having all plugs matched and installed correctly prevents future coolant seepage, bearing corrosion, and related cooling system failures.
