Has/does anyone use Pro Comp "shaft" mounted rockers on a small block Chevrolet engine? Are they junk or can they sustain high RPM passes?

I saw a post on YB before where a guy bought a set of pro comp shaft rockers and they didnt even have bearings on the shaft, they were just the aluminium body running on the shaft. Pay a bit extra and get a proven product that will not let you down. Why risk these things to save a few bucks? A broken rocker could ruin a whole engine.

Thanks everyone for the feedback. I heard these were junk but wanted to hear comments from some of you to confirm my suspicions. How about Probe Industries?
I think Probe rockers are now LGM....talk to Mark O'Neal or Shelton_Barrs on here.

It's fucking ridiculous that an Australian product can be bought cheaper in the USA than what it can be in Australia!

These aren't the only things either. *cough* ICE Ignitions*cough*

We sell a lot of Yella Terra through here.
We also sell Romac, RollMaster & JP Performance.
All great products.


The Aussie's need to build great products to race like this ...

The Yella Terra platinums are a good product. I have a set on my SBC for 2 seasons, no problems. One thing I would recommend is using lash caps. My roller tips were looking a bit worse for wear after 1 season due to a slight misalignment (the heads, not the rockers), lash caps have fixed that 100%.

And yes, what a crock, cheaper to buy in the USA than here in Australia where they are made!

The best shaft rocker arms there are, Jesel or T&D

But those sobs are SHIT!!!!
 
#26 ·
You are correct. T&D and Jesel are used in professional hot rods. However, they are very expensive. I know you get what you pay for but, some of us are on a limited budget. If I were building a 1,000+ HP engine, then yes, these would be the way to go. But for 500 to 650 HP street/strip car, I think the PRW or Yella Terra's might do the trick.

Thanks for the suggestion. I bought one of their harmonic balancers a couple years ago - no issues. Looking into their shaft rockers now as I found several dealers that sell their products near my home.

Look at prw shaft rockers 569.50...Very nice stuff....WWW.prw-usa.com.....The performance Quotient is nice stuff...

I've been using Yella Terra's with good results.Have broken a few of the older design adjusters,but the new design looks much better.Aren't the PRW rockers Chinese?
