PRW Roller Rockers Any Good?

Just curious what you guys think about the prw rocker arms, I picked up a set for my motor for 109.00 brand new in the box. Everywhere I look they are almost 200.00 so i couldn't pass them up. Im just going to be using the springs that came with my tfs heads ( double spring) . The cam I have is the Anderson B-31 so nothing too crazy.

Ive never heard anything bad about PRW. Then again, ive never heard anything negative about any aftermarket rocker manufacturer.

you obviously have never used proform or any of those eBay rocker arms...rocker arms arent something you spare cheap on just like that cam choice..i wouldnt have used anything besides harland sharp, crane, comp or even FRPP and jesel and a few other two..but no basic or cheap shit like that

The only reason i knew the brand was because they were used in a build up in a 5.0 magazine and they made some pretty sweet horsepower at anderson using these if i remember right 506 at the rear wheels with a s trim. Anderson sells the same rocker for 200.00 so i thought they might be decent

magazines number 1 priority is to sell parts, period. 99% of those magazine tests are a total joke and extremely biased, with being said, the down side is if the needle bearings come apart, then your in for a world of hurt. Seen it happen a few times with the chinese rockers and shaft rockers.

Show me a proform roller rocker that has failed because its construction was flawed. Infact, show me any aftermarket rocker that has failed because of its design. Im sure there are some out there, simply because everything has a point where its not perfect.. but how many times do you hear about them failing because they're machined poorly? Thats bullshit. I suppose Scorpions are junk, because you can get them on ebay, right? Ive seen "cheap" components, actually run and operate REALLY well, for extended periods of time. Infact, ive never seen a rocker fail, because it was a "POS". Proper assembly, maintence and adaquete oil pressure plays a big part aswell.

Then dont look at a comp stainless that doesn't have a cup for the pushrod, we have had pushrods weld themselves in the rocker arm because of this very problem.

I really dont think Anderson would sell those rockers if they were crap. Ive been really impressed with their products so far.

theres obviously something up if you can get aluminum pedastal mount roller rockers for under $150...

and jam...harland sharp has been around the longest...so $219 to me was well worth it...i thin cranes (not gold) are like $179

im not trying to jump in a fight or nuffin but i am running 1:7 pedestal mounts for $150 bucks............lol

ive got 5,000 miles on them so far, but when i first did the break in i took off the valve covers to take a look at them cause i thought maybe they were cheap for a reason, but they are perfectly fine, no problems yet

ill let you know in the future

and to tell you the truth i have held them next to harland sharp and scorpions, and they are the exact same looking, even tho you can be sure just by looks

looks aside, its the bearing that counts and the accuracy of the body, nothing more nothing less. For guys that are not looking for the utmost accuracy, the knockoffs are fine if you feel the need to risk a possible disaster to save a few dollars on valvetrain. On the flipside guys will buy the knockoff rockers and other items but buy other total nonsensical items for retarded amounts of money.

Thats the thing these rockers are normally around 200.00 everywhere you look, so in price they are comparable to cranes, scorpions and a few others. I was just stating the price I paid.

if you do a search on "Proform" on all the major boards you will see pics of failed units - they crack in half at the trunion bearing race.

Cheap and reliable don't go together. If you are going to skimp on something, don't skimp on a part that has the potential to fail and destroy other parts in the process. Skimp on something like an intake manifold instead. All of these cheap rocker arms have a failure history and like Tom said a simple google search will show you the facts. Even the low end Crane Engergizer rocker arms fail. I learned this when I tried to run them with 660lb springs. They don't like anything over .600 lift either as I found out when they starte breaking studs off because they didn't have enough travel.

My daily driver has 16 cylinders and 4400hp @ 1000 rpm....

thats cool...takes the drag racer and engine builder to say what i've said...for someone to listen...you might as well buy pre-bent pushrods...cuz you're gunna have plenty of those..PRW i've seen arent much better than proform...and anything close to proform...well isnt long for this life...like darrel said dont go cheap on you're valvetrain...stupid thing to do...
