1984-2012

like i told ya on the phone,i have the ultima`s in my 127" flh,and have used them in other builds.ive never had probs with them,but they arnt S&S quality

WFOLarry had responded on HTT about that he had some pocking. He didn't say how bad but I am curious, if he is getting pock marks is that really a normal wear indicator?

From companies websites.... JB ...HRK said that jirehcycles sells "seconds" not junk...

Definition of "Factory Seconds"



Definition:

When an item is listed as a factory second, it typically means that it failed the quality inspection at the end of production for a cosmetic reason. There is nothing intrinsically or structurally wrong with the item, but there is a blemish on the outside that prevents it from being released to the market as brand new. It likely has undergone testing to verify it is still in sound working order, and many times the blemish is hardly visible.

Advantages:

Often, consumers are able to get significant price savings on items listed as factory seconds. If you don't mind a small scratch or mar, you can find great deals on many electronics, clothes, games and even appliances.

Disadvantages:

Make sure you read each company's disclaimer regarding its factory seconds. The fine print can vary from company to company and occasionally the warranty may be affected; it may be nonreturnable and there may be other strict policies that need to be adhered to.



S&S:
Our forged steel roller rocker arms were designed for superior strength and to eliminate the failure-prone stress areas found in some other rockers. S&S roller rockers are forged from 8620 steel, heat-treated, and then shot-peened for additional strength and protection from fatigue. Our rockers also utilize 3/4" long bronze bushings, compared to the more common 1/2" long bushings or needle bearings. The end result is what we believe to be the finest rocker arm available anywhere, for any price. Fits 1984-up big twin engines, 1986-up Harley-Davidson® Sportster® models, and 1991-up Buell® v-twin and Blast® models.

Ultima:

Made from 4140 steel forgings, our new rocker arms are the strongest on the market today. These new arms incorporate a 1.69 ratio for increased lift and will match our Ultima® heads perfectly. A best value product. Uses OE rocker shafts.

and to throw a 3rd in for comparison...

TP Engineering:

TP Pro-Series® Forged Roller Rocker Arms TP Engineering's Roller Rocker Arms are forged from 4140 steel and CNC machined for a perfect fit. Each rocker arm includes solid bronze bushings for extended life, and roller tips that reduce operating friction so well they can give extra horsepower over your stock rockers. Pro-Series® Roller Rocker Arms fit all Evo-style, Big Twin, Sportster, and Twin Cam engines. Sold in sets of four.

Ultimately(no pun intended) JB the choice is yours

I deleted my last post as it wasn't needed. No disrespect intended and I apologize. Yep, understood of the seconds thing.... My head hurts....

Have a set of SE rollers and support plate with 3000 miles; made by Jims. You have my email, ping me if interested.

Email sent D

imagine all those small needdle bearings bouncing around in you engine, your valve train takes a lot of abuse when you twist your wrist. have 6000 miles on my 94 evo rebuild this year with se heads, roller rockers and 565 b/w cam. rev limiter 6000, abuse it every now and then, do not cheap out on a part with a lot of small parts, IMO

i agree,havnt been able to put my finger on it (maybe the "seconds" thing),but seen alot of probs over the years from JIERA crap

S&S roller rockers are cold-forged, then shot-peened to reduce further stress points (no one else does this). Also their bronze bearings are full length instead of only 1/2" at ends. Jim's (SE) are just as good.

I have not seen anything made in China hold up longer than it takes to open the package. They make things so cheaply that the products are a complete waste of time and materials. There are exceptions, but buyer beware.

Yeah I read this on the web site. I think that I have scored a set a set of SE rollers with JIMS support plates for a really good price. I will have to wait just a bit to get them though..

Are they new parts?
I wouldn't put someone's else used parts into my motor. There's prolly a reason why those parts are not being used. Hummm.
