Can't seem to find the answer to the following question-
Harland sharp rockers pn 5001, can these rockers support 3/8 dia pushrods ?
These spec's are not stated anywhere.
They were designed for stock style set ups with 5/16 pushrods.
Thank's in advance

 

Check their websight - I'm sure they're available.

 

3/8 pushrods have 5/16 ends so they fit

 

Can we get more specific? What type of head are you using? The HS 5016's or 5017's have a better design than the older 5001's. They provide a better geometry than the former. If you are using a 7/16" stud you may want to get the 5016's (1.6 ratio) or 5017's (1.7 ratio).
