High performance oil pumps are designed with high output and volume capabilities required for high RPM performance engines (see flow data chart). The gerotors are precision machined from steel-copper alloy (FC0205), an exceptionally durable metal that assures dependability and durability. Tight housing and gerotor tolerances provide optimum pressure and flow requirements. Housings are die cast DC-12 aluminum and are anodized to prevent corrosion. All pumps are individually inspected and tested. Free shipping to the USA and Puerto Rico via Ships USPS Priority Mail. Our non-performance pumps are equivalent to OEM pumps in design, engineering and metallurgy to meet or exceed OEM specifications.
