The "accessories" shown in red above must be replaced according to 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 billet, which makes them far stronger. In most cases CATCAMS camshafts are hollow, in order to reduce their mass.

CATCAMS expertise in camshafts and their accessories (valve springs, mechanical cam followers, vernier cam pulley, etc.) has been recognised worldwide for several years, thanks to genuine know-how and a precise study of engines and applications. Each camshaft profile has been developed around the specific features of each engine, but also around the intended use (road, sport, rally, drag, circuit, etc.).

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