Hastech Engineering's Porsche 911 & 964 forged rocker arms are a drop in replacement for stock rocker arms. Unlike stock cast rockers, these will not break if you have an over-rev or if used in an engine that will see high rpm use above 7400 rpm. Hastech forged rocker has a long pad follower and is based on the design used by Porsche for their forged rockers used in early 911 engines. These rockers enable the use of higher lift performance camshafts and also feature high strength bushings and DLC coating for low friction and long life. Hastech has used these rockers in all their race engines for years and are recommended for all aircooled Porsche 911 engines for both street and track. Learn More
