Description

Stage 4 - For customers seeking the cutting edge in performance water pump technology, Stewart Stage 4 pumps are the ultimate water pump for any application! In addition to all of the quality features found in Stage 2 and 3 pumps, the Stage 4 pump utilizes the Stewart Components DRV-8 impeller. The key to the water pump's performance. This exclusive 8-vane impeller is fully CNC-machined from 6061-T6 billet aluminum. It's special design flows up to 41% more water (up to 160 GMP) at TWICE the pressure of traditional designs, all while consuming less than 3 horsepower at 4, 500 pump RPM. Recommended for the heaviest racing applications.
