H.I.S. utilizes the expertise of one machinist throughout the entire process of rebuilding each cylinder. This policy optimizes the craftsmanship of our employees while assuring that each cylinder will have a proper fit. The rebuild process begins with a complete disassembly and thorough cleaning of each part. Before completion, each cylinder undergoes Òdry assembly,Ó final assembly, testing, and a minimum of two inspections to guarantee fit and function.

New Items
Hook Industrial Sales produces new, top quality cylinders with the best configurations in the industry. Pistons, which are bronzed, and glands have H-packs and G-rings. Rods and tubes are honed and chromed when needed. Mill type are standard heavy duty and durable to protect the inner workings of cylinders. Our cylinders are custom-made to our clientÕs specifications so they can be retrofit to existing mounting and porting locations.
