The "accessories" shown in red above must without fail be replaced in accordance with the CATCAMS reference (click on the images):

Unlike many of its competitors, which machine their cams from cast steel, CATCAMS cuts its camshafts directly from solid 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 pulleys and so on) has been recognised worldwide for many years, thanks to genuine know-how and a precise study of engines and applications. Indeed, each camshaft profile has been developed according to the specific features of each engine, but also according to the intended use (road, sport, rally, drag, circuit and so on).

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