The camshaft is a critical component that controls the opening and closing of the intake and exhaust valves in an engine. These valves regulate the flow of air-fuel mixture into the cylinders and the expulsion of exhaust gases. The shape and position of the lobes on the camshaft determine the timing (when the valves open and close), the duration (how long they stay open), and the lift (how far they open)
Aftermarket camshafts are designed with different lobe profiles compared to stock camshafts. These modified profiles can lead to increased engine power.
Kelford Cams represent the best in terms of tuning cam shafts and there are plenty of options for various brands and engines.
