Aluminum Water Pump - BBM

The MILODON Aluminum Water Pump for Mopar B and RB-Series engines, including the legendary 426 Hemi, is a mechanical standard-volume pump engineered for dependable cooling system performance in high-performance and classic muscle car applications. This purpose-built aluminum water pump delivers the flow characteristics needed to maintain optimal engine temperatures under sustained operation, whether in street driving, show use, or restoration projects where original equipment specifications are critical.

Built from aluminum construction, this pump balances weight reduction with proven durability in Mopar engine packages. The 5/8-inch pilot interface ensures proper mounting and alignment within the Mopar B and RB-Series block structure, maintaining precise belt-driven operation. Standard-volume displacement means this pump is calibrated for typical street and light performance use rather than maximum-flow racing duty, making it the correct choice for vehicles prioritizing reliability and balanced thermal management over extreme high-RPM cooling capacity. The natural aluminum finish resists corrosion while maintaining the aesthetic consistency expected in engine bay restoration work.

This pump is designed for Mopar B-Series (340, 360) and RB-Series (383, 400, 426 Hemi, 440) engine builders and restorers who require OEM-compatible cooling circulation without the cost or sourcing difficulty of original equipment. Whether completing a numbers-correct restoration, upgrading from a corroded core, or establishing reliable cooling in a rebuilt engine, the MILODON aluminum pump delivers the performance specification these platforms demand. At 3.79 lbs, it is suitable for engine swaps and custom installations where weight reduction matters without sacrificing flow integrity.
