Steel camshafts, supplied with vernier cam pulleys to fine-tune the intake cam timing.

Unlike many competitors who machine their cams from cast steel, CATCAMS cuts its camshafts straight from billet, which makes them far more durable. CATCAMS camshafts are usually hollow in order to reduce their weight.

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

Two parameters matter when choosing a camshaft profile: valve lift and angle (opening duration). Longer opening times give more power and torque, while greater lift optimises power at high rpm.
