I have a set of the cheap Crane die cast rockers on my Cleveland. The crane supplied poly locks keep backing off.
Is there a fix for these things? Are the $50 ARP polylocks any better?
I am seriously considering going to the BBC stamped rockers with the tension nut.....Or maybe the Comp Magnum rockers.[This message has been edited by Mpcoluv (edited 03-21-2003).]

Are your studs long enough? Do you have at least 1.5 x stud diameter thread engagement? {On a 7/16" stud, that would be 0.656"}------------------

Yes, I am running 2" long ARP 7/16 BBC studs.

Check the bottom of the set screws inside the polylocks that you already have.I have seen some that were not cut flat and square across the bottom. This surface must be flat where it seats against the ARP studs or it will loosen. Later,

Hmmmm, I have never had a problem unless it was stud or length related.
Regardless of poly lock brand.------------------
