No, they will need to be reground or you’ll risk destroying your cams.

New rockers through our host are $124 a piece without tax and shipping thus gets a little expensive times 12. I took all my rockers to a machine shop for steel bushing inserts, total cost for bushings and machine work was well under $200. Additional rocker grinding and polishing would be $300 for everything although I didn’t ask for regrinding as my cams were fine and my plan was to reuse them.

Supertec rocker rebuild process:

We remove the old bushing and adjuster (if present)
Clean adjuster threads with 8x1.0 forming tap.
Black Oxide the rocker
Ream the bushing hole
Press in the new DP4 bushing and burnish
Surface the contact pad
Coat the contact pad with Moly dry film (TLML 2)
Bore oiling passage
Treat the rocker to a Cryogenic conversion process

Plus One on this.

Henry, what is the exchange price for a set?

Also, what is Moly TLML 2? Couldn’t find it on the website.

Henry might know....

Brucerudin 12-08-2023 08:43 AM

Clearly. But not in the website and no answer yet via email. I did think and try that first.

Henry is most responsive to phone calls. I'd just give the shop a call today.

These thread live for ever and with prices changing almost daily, posting a price on a forum like this seems meaningless.
Call Supertec.

zztot 12-11-2023 12:32 PM

Prices
 
Agree….Henry is more than helpful and no muss no fuss. ……just call.

justjoshdyou 12-14-2023 08:42 AM
