A pistonis slidably fitted into the interior of the body. The piston is formed of ductile aluminum capable of being machined to a desirable shape and dimensions. The piston is hard anodized and PTFE coated for durable and silent operation. Hydraulic oil passage meansis formed in the body, and a capwith a pair of dual flow-through passagesis attached to the top endof the body for permitting the flow of pressurized hydraulic oil into and out of the interior of the body to effect axial movement of the piston. Hydraulic fluid may be transferred through one or more hollow mounting bolts.
