Febi HD Rocker arms

[digger]

maybe I'm getting different link but looks like he included bimmerheads ling for $348/set which is $29 each. They are about $23-24 everywhere else

My bad it’s a currency conversion

I got lucky and got 12 HD style ones from autohausaz the second time around

I would't call it lucky, they are garbage. Go OEM while still available

Too late now, but curious why you say they’re garbage? Have you experienced high failure rates with them?

20% off right now. I ordered 24 rockers while the price is good. Which is a good price as OEM rockers came with eccentrics and its hardware all ready do go. https://parts.bmwofsouthatlanta.com/?utm_source=google&utm_medium=cpc&adtype=&utm_id=1 8142295012&utm_adgroupid=&utm_targetid=&utm_matcht ype=&utm_network=x&utm_device=c&utm_term=&gad_sour ce=1&gad_campaignid=21179745077&gbraid=0AAAAADsJeS GXlAu2-07ncWR-t6pBz53ai&gclid=EAIaIQobChMIpJOEiKK3kwMVOF9HAR3hTh gpEAAYASAAEgKqefD_BwE

Interesting read. It's not clear whether the arms MM used were the same that Febi makes now. Idk if it was that thread or another one I found that showed some differences vs the IE HD ones. Either way, I'm running a stock cam so I think I should be OK.

The MM arms i used in 2006 and 2008 were not FEBI they were the same as the genuine OE it is possible that MM found out the supplier and purchased through another source

spring pressure is essential factor here too, especially for the first 30 min of cam break-in. With that being said, IE HD rockers that I had were a step better pad finish vs Febi HD. Febi HD pad was a porous mess. Made in China. OEM rockers aren't even close to both of them in quality of the pad finish, top notch.
For stock cam, there are zero reasons to go HD.. I can see high lift cam/ high revving engine maybe demands stronger rockers and one would sacrifice cam/rocker longevity for a sake of not breaking the rocker. But for stock cam, OEM rockers/springs all the way to keep your cam lasting. If you can, return them, splurge for OEM and sleep well at night. what I'd do
