Constructed from cast aluminum, the HardDrive oil pump undergoes CNC machining and a high-shine polishing process to ensure precise fitment and durability. This unit is engineered to split bottom and top-end oil supply, a design that increases oil pressure specifically for hydraulic lifters and upper engine components. By routing surplus oil back to the main supply passage instead of the return line, the system avoids unnecessary filtering cycles while providing a direct upgrade path for earlier engines to utilize the 81-up oiling architecture.
The kit includes all necessary installation components, such as gaskets, a drive shaft with keys and snap ring, mounting hardware, and both check ball and pressure relief valve assemblies. For riders seeking full customization, the pump offers optional oil supply fitting locations. However, for models equipped with oil tanks located below the transmission, routing through the stock locations is recommended to maintain optimal lubrication performance.
