Meant to say "Doug" Herbert in the title.

I did search before posting and only found really older threads on these. Butler site says these now have pressure fed needle bearings.

I'm experiencing the "price to good to be true" syndrome as they are half the cost of the other brands; why is this?

I spoke with Herbert Cams and they told me the same story I always used to hear about flat tappet lifters; in that there are only 3 companies that make the lifter bodies and so that apparently includes roller lifter bodies.

I caught a roller lifter axle starting to fail (normal end of life fatigue wear) after investigating cause of excessive lash (.048) on #2 exh and .035) on #1 exhaust. All others were holding their lash right where I left them. These were used Crane lifters and I don't know the usage history on them.

So I'm in the market for a set of roller lifters and regardless what goes back in the lash will be checked after every race/.drive to keep eye on things. I am considering these Doug Herbert pressure fed needle roller lifters.

Anybody know why they are so inexpensive compared to all the other brands and does anyone have any bad stories to tell about the newer Doug Herbert pressure fed needle roller lifters.

Hoping to hear good things ...thanks!

Added picture of worn Crane lifter just for general interest of roller lifter wear stages. At this stage the needles were still all intact but their surfaces were rough and no longer like glass; the wheel was nice on outside with slightly rough bore that matched the needles surface condition.
