ebay rockers? i was looking at lsx parts on ebay and came across a bunch of cheap roller rockers. i found them in aluminum and stainless. i was wondering if anyone has any experiance with these rockers? do you think i should trust them? they seem to be a good product but i'm not sure. i want some full roller rockers but can't see spending $400 on set.

Meh, I wouldn't be the test dummy for those. The first set doesn't look like any real R&D went into them. The second set looks like a mix between a comp and yella terra. On top of that I don't see any numbers from any testing.
FWIW you can find comp rockers for around 350 in the for sale section. I know you don't want to spend that kinda cash, but if your changing them, you might as well get something thats proven.

Considering the yella terra's rockers quality and price from New Era performance buying anything else is a waste of $. I would not gamble my motor on ebay crap! If you really want rockers and dont want to spend about $369 to $400 send your stock rockers to harlan sharp!

Some of the rockers arms from off shore have bearing issues. We have had several companies want us to carry their rockers. We get samples in here and they all seem to have the same problem...the bearings are too loose. We carry only Harland Sharp and now Yella Terra. Both of these rockers can be purchased from us fo $400 or less. Both of these are from proven companies. Please give us a call if you have any questions.

Enough said!!
with the customer support that Patriot has, and their low prices on quality proven pieces is all I would like to hear.

get the shafty yella terras man,their the only ones I trust,then again

I try to reason with any given name branded products
+ even the no name products on the test mules
such as my own cars where its within reason.
after all ,I like to give the new players the benefit of the doubt.
and co operate in further developments to ensure quality control
is pertained.
Its very dissapointing where you see a brave man go out of his way
and spent countless of hours and driving to the equation
utilising certain new products,taking the risks for the sake of others
only to have someone hit back with a claim that concept wont work,despite ample proof that indeed they do,such as the case with the stainless ones.
I am not on an agena to enter into the they vs them ,but rather I will ordain to the concept 100% no questions if they are presented to me otherwise.
After all i had zero failures with anything that came from michigan
or other areas in the beaut usa.
with out them there is no way i would have gotten the same reliabilty from the oz v8 engines
As far as the rockers mentioned are concerned ,I dont have any drama
with nascar proven performers(peiod)
However i have reservations in one engine which i cannot conclude
if it was a case of bad batch or just a case of the idiot engine builder whoms name i wont disclose to cover his sorry ***
I didn't build nor was involved with that boat engine.
The bloke that ran em,arose to some crossfire or detonation
issue that eventually locked the engine before the boat flipped over.
according to dave the revs never exceeded 7000 rpms.
From what I saw of the rockers, it was not a roller bearing related issue + that engine ran a roedeck block with a 262@0.50 cam which didn't imply to me that revs were the issue either,and so it ought not be
But somehow, something very nasty happened with a big miss in the
combustion process, that must have compounded to some awfull
valve train events that eventaully broke the rocker shaft mount areas
in a few different places.
I cannot remmember exactly the whole extent of that failure,other than the bore was still ok. which certainly cut down alot of the swearing around the place,then things got quiet untill he proceeded to hone the bore.
I do remmember the darkish heat treated mounts and thats all i can comfirm
that i saw that was broken.
Its not a case of not trusting the rockers but i guess if the valvetrain
had the strongest componentry which that engine indeed did,it will eventually
give out somewhere if the tolerances were exceeded.
Id rather think that his pushrods were stronger than the jessel mounts,rather
than the jessels mounts failing on their own.
Conversely i wont argue with anyone who trusts them,but will err on anything
that compromises the the outlay of the expendeture within each engine.
If the customer wants em,sure why not?if money is no object
the jessels will be added to the option list.
Conversely there are other ways to skin the cat too!
this where yella terra and the likes of other proven rockers go hand to hand
with making more power,so natrually I will reccomend them first on a limited
funded race engine.

I bought the 1.75 stainless rockers listed up top. They seem to be pretty well built and the guys at shanons racing were really helpful. Can't beat the price... So we'll see how they work. If you check his feedback there's quite a few people who bought them so I'm sure they're on a few engines of people on this board...

Do Not Buy!!!! For starters....THEY ARE JUNK! I bought that exact set from that exact guy. They will not fit an ls1. They said we sell thousands of these. Refused refund. I contacted the CAT company that manufactures them. They exchanged and upgraded me to stainless steel. I paid shipping 3 times! I had more in shipping than in the rockers! Stainless steel ones do not fit ls1 head either so i took a bunch of detailed digital pictures to send to them. They called me a liar and said i only wanted freebie! Then i got a nasty msg from woody H their tech guy saying he doesnt want to **** my ugly mother out of no where! I would no buy anything from them. They will not give you a phone number to speak with them over the phone. Only reply in nasty emails to you and their product is JUNK!

The money you think you're saving may end up costing the price of a top end down the road. The first set on the surface looks like a deal, but don't forget you have to use guide plates or girdles on any system the uses polylocks so that runs the cost up further. Additionally that set looks highly questionable from the description plus the fact that they are so ashamed of their product that they won't even mention the brand name. Not a good sign. The second one appears to be of better quality, but personally I stay away from ebay. I strictly deal with the sponsors you see here on LS1Tech and there is a reason for that. If I have to explain the reason you might be better off sticking with ebay. Out of all the rockers shown the ones from Raceparts appears to be the best. If you can get them for that price and Jegs sells them for twice the cost you may have actually found yourself a real deal. The thing is with those your back to the original price point you were trying to avoid in the first place. I realize that there is a big markup on GenIII parts because it's the hot engine to modify these days, but that's what happens when you're the new kid on the block. I'm always curious when I compare prices between a similar GenI part and the cost for the same part on a GenIII engine from the same supplier. Sometimes the price difference can be as much as 50% so I can understand when people try to save a few dollars, but are you willing as has already been suggested to allow youself to be a guinea pig. If so good luck. Just grit your teeth and keep your fingers crossed and if it works out you can come back and say "I told you so".
