LOW-FRICTION COATING

Many steel billet components, including camshafts and followers, can be treated to a low-friction coating. These coatings not only reduce friction between moving parts (thus reducing wear and increasing reliability), but they also help to reduce engine operating temperatures. After all, any form of friction will create heat, and by reducing friction, you’ll reduce heat. Perhaps unsurprisingly, low-friction coatings are costly, and tend only to be used in motorsport, where maximising every last bit of power is essential.
