why do people keep buying this junk? by the time you buy theese, then replace them with others, it would be cheeper in the long run to buy good ones from the start. not to mention the cost to repair the damange caused by the failure of junk.....

Pay now or pay later... Just check the stress/workload the valve train has to handle.. Next bring up the RPM.... Not the place to cut corners, use quality components... Just my $0.02...

I bought a set a few years back...looked at them and desided they we not what i would use on a race motor. I had HS on the Duster and for years Crane Golds on the Arrow...the Cranes held up well but I did go back to HS this year.
5.53 @ 125 1/8th on the launch control..more left in her!

I like a lot of their stuff and use it, but rockers, lifters, locks, and retainers are NOT the place to go cheap. 440source has made Mopar performance parts affordable, but you have to use discretion in how they will be used and which parts you are actually considering.

Some guys were talking about the "PRW" brand rockers a few weeks ago. Dunno what the consensus ended up being on those. It didn't sound all bad.
I have been bidding on some old Crane/Isky/Erson ductile iron rockers on Ebag for a few weeks now. They've gone up and the price of new is pretty startling.
Soooooo, I just got some Harland Sharps from Mancini Racing. These are the "Exclusive" ones, supposedly, only available from them. They advertise them as a "bushed type" but there's NO bushing just a "non-roller" set-up. Which is OK by me since I'm not going over .600 lift for my deal. The shafts look real nice, appear to be hard-chromed and very thickwall (less flex).
So, for a little more than the PRW's, I bought an American made (as far as I know) rocker system that will not disintegrate under useage.

Crane use to call those type rockers "Extruded aluminum roller tip rockers" They will break on the bottom if misused, roller cam with a lot of spring pressure(600+ lbs) and RPM(6000+ RPMs)
OP, I bought several sets of CAT brand alumimun full roller rockers arms(Harland Sharp Chinese clones  ) several years back before it became known that they where not that great I put one set on a set of Speed Pro H.D. chromed rocker shafts in a solid roller lifter cam motor, the rollers ate the shafts up real quick   I have since bought several sets of the 440 Source roller rocker shafts so I can use those rockers on a hydraulic lifter motor for myself with 350 Lbs open pressure, I'm hoping that works out  If not they all (four sets)go in the trash

I used those Crane rockers for years with ZERO problems
and ran 8000 RPM with 720 psi open(those were the
rockers MP sold for many heads... I used them on my W-2s)

So did you call them and ask where your bushing are ? If they are advertise that they are. I would been upset if they did't come that way. I been thinking about buying a set of them.. But this might change my mind.

The PRW rockers are cheapo..
@ the Long Beach Swap Meet full sets are selling for $125. I guess if one is on a tite budget and driving only street maybe one can get away with them..
Regarding the Crane ductile iron rockers sets sold by Mopar about 5 years ago just before Crane went bankrupt...
Be careful, they had a major quality problem where the valve stem would wear through the rocker contact point due to a faulty hardening process. We had several wear issues and went back to Mopar and Crane engineering and they just gave us the sunshine treatment....
Tossed them in the dumpster, spent the $ and installed Harland Sharps...
If you guys had any idea of how many complaints/returns 440Source gets you would move on to another brand..
Just my $0.02...

Exactly, why do they? With he amount of cash to build a decent power plant, it doesn't make any sense at all to use the cheap sht, yet they do. Some think it's OK for a street motor but that application has the most cycles. It's just that, junk. JMO
