What is the most durable roller lifter.

Not interested in the cheapest. I want one that will last like a set of valve covers.

Any suggestions?

I agree...all the big companies make excellent lifters....Crane, Lunati, Comp Cams....alot of guys (including mysefl) are running the CC's "R" lifters.

Dude, Nothing last forever.

I have accepted that fact. Everything has a cycle life.

Just looking for a set that will live at a constant high rmp environment for extended periods. Not 10 seconds at a time.

I have heard stories of the name brands comming apart and ending races and destroying engines.

I would believe that the valve train is the most highly stressed componet of a pushrod engine and want the best reliability possible.

Hydraulic or solid? Factory or retro-fit?

1970 s era block prior to OEM roller cams.

Solid lifter.

Non street application.

Road Race only.

Thanks for clarifying my request for info.

nothing aluminum,after much research and discussion,i would give the comp pro-mags the nod.

He's looking for lifters, not rockers.

I don't have any experience with solid rollers, but I imagine all the cam manufacturers would have something suitable. Comp has the "Super Roller" series, for example.

How does a solid lifter "come apart"?

Apeiron

The axle fails, and then Bad Things happen.

I guess you could consider that "comming apart" I would consider that breaking. Oh well silly me being all technical. To The Top for You.

No experience myself, but I spend alot of time at www.chevelles.com and there are alot of very experienced people there. Most of the solid roller lifters out there do not lube the roller axle, just spray oil on the roller itself. From what i've read the Isky Red Zone's do lube the axle and last alot longer then other brand lifters. Several machinists there only recommend them. If you do a search on their performance board you'll get alot of info.

Comp's Endure-X lifters also supply pressurized oil to the roller, and I'm sure Crane has something similar. They're intended to keep the roller lubricated during low-RPM operation on the street, though.

there is an axel-less roller lifter available. It used pressurized oil to form a hydraulic (just like a bearing) wedge between the roller and the body. One less point of failure and NO needle bearings to grind up your engine.

SDIF

Thanks for the info on the lifter that are pressure oiled vs. splash.

This is great to know.

Also thank for the bearingless roller info also. I have read about them too but did not want to bait anyones responses.

Your input is greatly appreciated

Those bearing less rollers are the Roller X lifters and from what I've read are the only things you would want if it see's extended high rpm blasts over a long period of time.

who makes those bearing-less roller lifters? anyone here actually use them? curious what people with first-hand experience say about them.

Apeiron

Schubeck. They require machining of the lifter bores.

crower makes one the best roller lifters on the market.i have the severe duty cutaway style with the high pressure pin oiling option.

550 bucks but worth every penny.
