Are you a mechanic? Are you making a performance engine for races? If yes, then you will always want the engines to give the best revolutions – more revolutions per minute increase the airflow and subsequently make more power. RIght? To achieve such results, you require stiffer valve springs, stouter pushrods, and stronger roller rockers.
A roller rocker is a fulcrum-style oscillating lever that, along with the lifters and pushrods, transfers the radial movement of the camshaft into linear motion to open the valve, and the roller rocker also allows the valve-spring to close the valve. In over 40 years, the design of roller rockers hasn’t changed much, only the material has improved, and bearing designs are updated.
Thus, a mechanic must keep in mind the importance of roller rockers in an engine and do the shopping. Now the question arises which roller rocker is the best among the different varieties available in the market? So here is the article for all the answers, wherein we have described the best roller rockers for SBC.
