LS EWP Block Adapter GM GEN III IV LSX

The LS EWP Block Adapter GM GEN III IV LSX by Davies Craig is a precision-engineered cooling system component designed for engine builders and automotive enthusiasts upgrading to electric water pump (EWP) configurations on Gen III and Gen IV LS platforms. This adapter bridges the gap between modern EWP technology and traditional LS block mounting points, enabling builders to eliminate mechanical serpentine belt-driven pumps while improving engine bay thermal management. If you're pursuing a cleaner engine bay layout, reducing parasitic drag, or building a custom LS-based engine for street or race applications, this block adapter is a critical piece of your cooling system puzzle.

Davies Craig's LS EWP Block Adapter features precision CNC-machined construction to ensure accurate bolt-hole alignment and leak-free operation when mated to both Gen III and Gen IV LS blocks. The adapter integrates with Davies Craig electric water pump units, allowing independent pump operation controlled by engine ECU logic or auxiliary controllers for optimal coolant flow without engine speed dependency. Cast aluminum construction provides durability and thermal stability while keeping parasitic weight to a minimum—critical when optimizing power output and reducing mechanical losses in high-performance LS builds.

Engine builders working with LS2, LS3, LS7, and LSX block variants will find this adapter essential for electric pump conversion projects, whether for road racing, autocross, street hot rods, or engine swap platforms. Installation requires basic mechanical skill and familiarity with LS cooling system configuration; the adapter mounts directly to factory bolt locations on the engine block. Compatibility spans the entire Gen III and Gen IV LS family, making this a versatile upgrade for builders standardizing on Davies Craig's proven EWP technology across multiple platforms.
