Roller rocker arm assemblies were originally developed for the Datsun roadster in the mid to late 1980's into the 90's by Datsun engine guru Dave Weber, now deceased, at Malvern racing. They were manufactured and developed by JB racing in Florida and were offered in different rocker arm ratios. The ones supplied here were not the first roller rockers available in the world, but are of the highest quality available.
These fully assembled roller rocker arm assemblies first appeared in the late 90's from Rocker Arm Rebuilders of Torrance.
