Upgrade cooling performance with the Pro Circuit Water Pump Cover with Impeller, a CNC-machined billet aluminum kit built for strength and long-term durability. The included impeller is designed to increase coolant flow and help reduce hydraulic friction and cavitation for more consistent engine temperatures.
Upgrade your engine’s cooling system with a stronger, high-performance water pump solution. The Pro Circuit Water Pump Cover with Impeller is CNC-machined from billet aluminum to deliver a rigid, lightweight, and durable replacement that’s built to last. By combining a robust cover with an impeller designed to increase coolant flow, this kit helps your bike manage heat more efficiently—especially under demanding riding conditions.
If you ride hard, spend time in slow technical terrain, or simply want more consistent cooling performance, improved coolant circulation can help stabilize operating temperatures. The impeller design is engineered to reduce hydraulic friction and cavitation, supporting smoother coolant movement and more effective heat transfer.
