HD Water Pump Assembly

The HD Water Pump Assembly by K.S.E. Racing is engineered for high-performance and racing applications where reliable coolant circulation and thermal management are non-negotiable. Built for serious engine builders, drag racers, and track-focused enthusiasts, this heavy-duty water pump assembly replaces OEM units that struggle under sustained high RPM operation and elevated engine temperatures. Whether you're running a modified street engine or a dedicated race platform, this pump maintains consistent flow rates that prevent hot spots, cavitation, and catastrophic cooling system failure.

K.S.E. Racing's design prioritizes volumetric efficiency and durability through precision casting and optimized impeller geometry that maximizes coolant displacement across the entire RPM band. The assembly features robust bearing support and enhanced seal integrity to handle sustained boost pressure and aggressive coolant additives without leakage or premature wear. Internal passages are sized to reduce turbulence while maintaining laminar flow, directly improving heat transfer efficiency compared to stock units. This pump's compact footprint—measuring 8.35 × 7.95 × 11.15 inches and weighing just 4.18 pounds—allows installation in tight engine bays without requiring extensive modifications.

Racers and performance mechanics choose this HD Water Pump Assembly for supercharged, turbocharged, and naturally aspirated builds where conventional cooling systems fall short. It integrates seamlessly into vehicles with existing K.S.E. Racing-compatible engine platforms and delivers measurable reductions in peak coolant temperatures under full-load conditions. Installation requires standard mechanical tools and basic knowledge of engine bay work; verify pulley diameter and mounting bolt configuration against your specific engine platform before ordering to ensure proper fit and alignment.
