Crower Aluminum Shaft-Mounted Rockers

Each of Crower's Aluminum Shaft Rocker configurations is impeccably designed and produced to maximize valve train rigidity and accuracy while offering a minimal amount of reciprocating mass. Crower uses the longest arm lengths practical for each application. The results are minimal rocker tip travel and associated frictional losses as well as the capability to accommodate large diameter valve springs with ease. They are available in several assembly applications including AFR, Dodge, Edelbrock and others.
