Pair of Competition Distributing's Offset Endurance Rockers
These rockers have a larger offset than the stock versions allowing your intake valves to open further and increase airflow.
Case hardening of the arms to increase wear resistance. Oil Impregnated bronze bushings on the pivot and Aircraft Grade hardware with encapsulated lock nuts.
These will work on Harleys from 1915-1929. You just have to add the larger push rod end for the earlier models. (PART # 136-28)
They come with the alemite fittings installed.
