Interesting idea. Not sure if "roller lifter" fits it but does show promise. Keep us informed on further progress.

Hummm...? Could be the answer to flat cam lobes because of the removal of zinc in our oils...?

Like to see the cost and long term durability...?

about $700 for a set of 8 they're in testing stages right now jeff said he will keep in touch so will post more info as it is available

jeff also said he uses brad penn racing oil in flat tappet engines to reduce friction he is a distributer for them

here's some more info on another guy making the same type of lifters


Schubeck rewrites the Book on:
"The Care and Feeding of Flat Lifters!!"

The Discovery of a Space Age material used in the production of Schubeck lifters, not only raised the bar for higher competitive achievements, but justified the reason for rewriting the book on "The care and feeding of flat lifters". All the rules handed down through the years, deemed necessary to make a flat cam and lifters survive, no longer apply.

Rules such as:"Flat lifters need a tedious break-in process in order to survive" and

"A lifter should never be separated from the mated cam lobe after break-in", not any more.

Now using "Schubeck composite flat lifters". You just install the lifters on your new or used cam, raise the spring pressure, if you desire and go to the races. You can also experiment with different cams as often as you like, using the same Schubeck Lifters, again and again.

Soon you will disregard the rules that we were all taught over the years. Yes, you will develop new confidence that they no longer apply. The're will be, No Break-in, No Lifter Wear and No Cam Wear. Go to the track with your mind on more important things.

i'm just using his lifters as an example ok because i read what GUY HILTZ SAID
