Unlike many of its competitors, which machine their cams from cast steel, CATCAMS cuts its camshafts directly from billet, which makes them far more durable. In most cases, CATCAMS camshafts are hollow in order to reduce their mass.

The expertise of CATCAMS in camshafts and their ancillaries (valve springs, mechanical cam followers, vernier cam pulley, and so on) has been recognised worldwide for many years, thanks to genuine know-how and a detailed study of engines and applications. Each camshaft profile has indeed been developed to suit the specific features of each engine, and also the intended use (road, sport, rally, drag racing, circuit, and so on).

Two parameters matter when choosing a camshaft profile: valve lift and the angle (opening duration). A longer opening duration increases power and torque, while more lift optimises power at high engine speeds.
