I've read a lot of posts on this forum and others about roller rockers. I've also talked to my machine shop and hughes, harland sharp and mancini. My budget is about $800. My lift should stay at .600 or under. The car will be wide open throttle as much as possible but will be a street driven car. Im looking for the best, most durable, longest lasting rockers in my price range.
From what Ive heard and read, Im leaning towards the hughes aluminum and Im interested to know if the cryo freezing is just a gimmick or if it's all they say it is. I almost went with the comp ultra pro magnum steel rockers but I read on their site they are needle bearing type and Im shy to that type. My other option was the crane ductile aluminum, but I read the new ones are not built as well as the old style. Then, there is the Mancini labeled harland sharps, they are the best price out of all of these, but havent heard from anyone who's used them. Am I missing any? I have no experience with any of these setups, and havent seen any recent threads on them... anything new or changed with any of these rockers that I haven't read about already?

Personally I would never run a rocker that wasn't either bronze bushed or roller bearing. I don't like running aluminum on a steel shaft - seen too many cases of galling. I don't know what your concern would be with rollers bearings. As for cryo treatment ... it works. Whether its needed or worth the expense is entirely personal.
 If you go with an alum body rocker bronze bushed is the best , get banana groove shafts also.

nothing beats stainless... I have run the same crower enduros on a gm engine for 10 years @ 1:65 and 1:7 ratios with no issues ever .7500 rpm oval track punishment at that. bent plenty of valves but never had a rocker failure.

After the 'customer service' I observed from Hughes several years ago, they wouldn't get a dime from me...
HS...
They wernt very friendly w/me when I called, and seemed pretty annoyed when I asked some technical question about their products. But I've never heard a bad thing about their rockers

My concern with roller bearings is longevity. It seems like most of the forces on the rocker arm would be concentrated on only some of the bearings and would wear them faster than the others. I was very interested in getting steel or iron rockers and getting them bushed, but I've only read about 1 place that does it, RAS, and I have no idea if they still do it or if its even the same company or owner

The Comp cast alloy steel "pro magnum" rockers may be just right for your application. Durable and work well as shipped up to about .6" lift. Higher lifts and pressures benefit from a bushing. I'm running a set on a 496 with .55 lift and no problems.
See I thought these were solid rockers that could be bushed, but they are actually needle bearing rockers

I was planning on buying Comp's Pro Magnum rockers a few years ago, but decided against them because (if I remember correctly) they're bushed and DON'T have needle bearings. I could be wrong, though...
I ended up going with Harland Sharps. The guys on the race board swear by them and I haven't had any problems with them so far. But I would be sure to make sure clean and inspect any new rockers you buy for shavings (but especially the Harland Sharps).

the neddle bearing rockers will never wear out . they will carry any load "you" plan to put on them. get a set like the crower enduro's in STAINLESS STEEL and never buy another set.
This advice won't help.
He's looking for shaft rockers so he must have a SB or BB. The only rockers Crower makes for Mopars are for the stud mount V8 Magnum and V10.

I think RAS is Rocker Arms Unlimited now.

I have 2 sets of Hughes Roller rockers. 1.5's on my hot street 318 for 2 years now, 4000 miles. No issues.
1.6's on my 408. They are a very good rocker. Hughes customer service has always been good to me...
