The "accessories" shown in red above must imperatively 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 more durable. Most of the time, CATCAMS camshafts are hollow in order to reduce their mass.

CATCAMS expertise in camshafts and their accessories (valve springs, mechanical cam followers, vernier cam pulleys, etc.) has been recognised worldwide for many years, thanks to its know-how and its precise study of engines and applications. Each camshaft profile has been developed according to the specific features of each engine, and also according to the intended use and application (road, sport, rally, run, circuit, etc.).

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.
