Schubeck lifters question?

Post by pdq67 »

I recently read somewhere that Schubeck had a partner in his lifter business?

Anybody know who he was?

And is Schubeck even still around?

Oh, I finally found out what they made their , "ceramic' lifters out of.

"The Shubeck lifters were sourced from Ceradyne in California and made from Silcon Nitride. As the war in Iraq ramped up Ceradyne dedicated all resources needed for vest plates and armor for DOD. Shubeck was essentially cut off. The Shubeck lifters had their own problems in certain uses. There are threads discussing this. Try the search function."

When Schubeck closed, SM Lifters (Smith Machine LLC) took over making them, and apparently he was an employee of Schubeck's. The shop went to Oregon. His phone number was (a few years ago): 541-942-5920. They were marketed as SM Lifters. Apparently no longer.
4 seconds flat now has that phone number. They don't list ceramic or any other lifters for sale. Although they did years ago and a member on here was running that company, had a link to his website with ceramic lifters etc.

Having said that, listen to rebelyell above^^^^

We tried the SM lifters, bought brand new from Smith Machine, correct springs loads, on the second dyno session, a ceramic foot ('puck') got scared and decided to get the hell outta there. Operator caught it quick, shut it down. Damaged a few internals, not good.

DON'T USE THEM even if you can find some.....

USE Tool steel with DLC coating, period. Trend and a few others sell 'em.

But you knew all of that from 10 years ago when you asked similar questions about this same lifter pdq67....the search function is great.

What was the 'problem' they were trying to fix? Weight?

They were/are limiting weight but more importantly a FLAT lifter that can survive extreme high spring pressures and fast, hi-intensity lobes.

Only in last few years were CUP cars permitted rollers lifters; prior to that, their Very expensive flat lifters & cams were seldom trusted to survive a second race. Also, rear gear mandates Lowered max rpm. With flat lifters, it WAS common for Cup motors to see +10K lap after lap after lap. It's lower today.

Yes, trucks & busch got rollers first; somewhat as a testing ground and reduced annual valvetrain budgets. Proved out, then cup got em.

In addition to Trend, Vern Schumann manufactures great lifters as well as some of the best wet sump pumps.
