ACL 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.
