I encountered these while looking for 1.7 rocker upgrades to my engine. For about $275 more, I can get a Probe set ($539)...so I thought why not! Jessel and T&D also make them, but they are more expensive.

probe shaft rockers

No more guide plates, perfect geometry, easier to adjust my solid lifter lash.

Then you've got these...CATs for about $300. They also come in 1.7 ratio. So what's wrong with them?...anything? Ebay buyer beware?

CAT shaft rockers

Anyone using Probes or CATs?

irregardless that I sell probe/coasthigh, cat and pro comp I would NEVER use in the valvetrain. Those bearings let loose and it will cost you dearly. Just my2cents

Heres a direct quote from a member, mind you its pro comp, same junk

"what kind of warranty does pro comp stuff have? i bought some shaft rockers, put less than 1500 miles on em, and they are fuked. can you help a brother out?"

Haven't used the Probes but I would recommend staying clear of the Chinese stuff. IMO The T&D & Jesel stuff is more expensive, Yes, but proven. How many Pros run CAT parts?

Never mind on the CAT stuff. I should have known better. I'm hearing how they start to fail and fall apart after 1500 miles...sounds like junk to me!

New abbreviation YGWYPF (you get what you paid for).

I use Jesel all the time, but I was very impressed with the Probe stuff. It looks real nice, almost just like Jesel. I have sold 4 or 5 Probe shafts with NO problems. JOE SHERMAN RACING

I think it's interesting to remember way back in the mid-50s with the 1954 Ford V8 Y-block having the then traditional shaft rockers while the 1955 SBC came out with "ball socket" stud mounted rockers. Everyone back then regarded the stud rockers as the great technical advance that gave the SBC an advantage over the Ford. This was not actually true, but we all thought it was! Anyway, when Ford came out with stud rockers in 1962 (221 cu in Fairlane V
, we Ford guys breathed a sigh of relief that we had a competitive valve train. Then surprisingly, Ford went back to shaft rockers for the 1963 225 cu in aluminum Indy V8 (based on the 221/260 Fairlane V
. What the heck! Why did they switch to those old style shaft rockers for their Indy V8? Anyway, everyone knows better now; but it's nice remember what was general opinion in the old days.

If you are a member of the hardcore50 site, you can get the Probe stuff for $485.99. It is supposed to be a pretty good setup nowadays.
