Rocker arms
Sorry it took so long but thanks to all responders. I found out what`s up with the extruded stuff by another member on another thread, same page.
I decided to go Hughes,with their hold downs. Ordered 4/18, have yet to see them. I`ve been politely contacting them, and they keep saying to check back later in the week, saying shaft machine`rs, are still working on them. Being impatient, I told them last week that if they don`t ship by friday, I`m considering cancelling the order. They responded by saying, threats won`t make em ship any faster,apologising and to check back the beginning of this week. I`m getting tired of being jerked around. Their site still says on backorder, est. delivery on 4/28. I could of had the pro mags from summit and been driveing 3 weeks ago. I say just be upfront and honest on a ship date instead of stringing along a customer for weeks on end. Bad business practice if you ask me. What say you? Am I being unreasonable?:argue:
Heres the deal
Probe made the rockers for hughes.
Hughes decided to try and cut out the middle and bought all the tooling to make them all by there lonesome....but they had no idea how much work it was and how many people it took to run the machines....so now they have zero rockers and pissed customers.
They are in over their heads...
Extruding tightens the grain structure & makes the aluminum harder 'in a nut shell' btw
The hughes rockers do not like large valve springs and may contact the retainers just like ALL other aluminum rockers that are on the market-crane/prw/procomp/HARLANDSHARP/kmj/ohio crank....etc...
The majority 'with the exception of 'hughes/probe/t&d/jessel/crane' are more than likely ALL MADE IN THE SAME FORGERY...even the harlandsharp rocker bodies 'besides the minor finish machining diff' ...if you look at them, the bodies are the same with just a different anodizing ...the needle bearing types all take a 146 incased roller bearing, wether this or that company makes that 146 bering doesnt really matter since they area ALL held to meet the same standard.
Comp rockers have been revised from the original pro mag to the ultra because some people who were running BIG lifts with LOTS of spring psi were having shaft/rocker bore galling issues 'the rockers were wiping out and transferring metal to the shafts -hughes mentions this fwiw...then they go on to cover the competition by saying that the PRW comp style rocker that are bushed have poor geometry...they wouldn't want you thinking you can get a lower cost rocker that addresses the galling issue with bushings cause then they would lose $$$$
the only rockers that have honestly been proven time and time again to be total pieces of sht are the PROFORMS/440 SOURCE/INDY ROCKERS, the rest simply have been tainted by the 'over spray/pigeon holing' coming from fear mongers rants on how they fall apart into your engine therefore you should have spend 500+ on rockers for a street engine.
I have been running the chinese needle bearing rockers for a couple of years, only issue I ever had was on 1 of the rockers having too much side play 'my fault', which let the need bearing move side to side over and over again and wore the race some, but still.... no failure, no catastrophe, nothing but me replacing the one rocker.
There guys are this site who drag race yrs with the same set of chinese rockers with no issues.
The key is good adjusters and proper setup, if you dont do this...that your own fault.
