Camshaft

The camshaft is a rotating shaft fitted with carefully shaped lobes (or cams) that open and close the engine’s valves at specific points during the combustion cycle. It must be precisely timed with the crankshaft so that each valve operates in perfect harmony with piston movement.

The camshaft is typically driven by the crankshaft through a timing belt, chain, or gear system. Engines can have a single camshaft (SOHC) or dual overhead camshafts (DOHC), and they may be located either in the engine block or in the cylinder head, depending on the design.

Wear on the camshaft lobes, journals, or bearings can result in poor valve timing, reduced engine performance, rough idling, and increased emissions. Severe damage may cause valve and piston interference, leading to costly engine repairs.

Key features and uses:

• Coordinates valve timing for intake and exhaust

• Affects engine breathing, torque, and fuel efficiency

• Made from hardened steel or cast iron with machined lobes

• Works with lifters, pushrods, and rocker arms in valvetrain systems

• Available in various profiles and specs for specific engines

At Sanders Parts, we offer high-precision camshafts designed to match OEM specifications — delivering smooth valve operation, optimal timing, and reliable power, every time.
