Anyone using these lifters from Revolution Performance. They call them Revperf "Hydro Rev". This it what they have to say about them. " These lifters feaure a unique hydraulic anti-pump up race retainer designed to precisely limit plunger travel and replace the cheesy OEM retaining clip. The roller and axle are manufactured of bearing quality carbon/chromium steel and feature needle bearings for ultra smooth rotation. The pushrod seat is carbo-nitrided for extreme durability and the lifter body itself is a high quality, super strong steel billet body, CNC machined for strength and durability. These lifters also carry a lifetime warranty! If the lifter ever fails we replace free of charge!"

Yes, I am. Haven't had them on long (1500 miles). So far, so good.

rlpos · 07-09-2007, 05:25 PM

It is what is in my GMR build. Over 9000 miles on them.

I've heard they are good lifters, although the stock Harley lifters are fine for just about any build, even in my drag bikes. I've never had a problem with stock lifters and they cost a little less.

If you use the newer style OEM lifters, you won't have any problems with oil pressure or anything else. My bike's pressure is usually around 2-5 psi idling when it's really hot. That's plenty of pressure at idle. It'll get up to 25-35 while cruising.... also fine. If your lifters are bleeding down overnight, that's not a big deal either, as long as they pump up soon after starting the engine. Like I said before, OEM lifters are fine, even for race applications. I haven't changed the ones on my 1995 EVO in over 35k miles (except for one that the bearings crapped out on) and they are still working fine.

Good except for the bearings...?

oil pressure is about 5-7 pounds at idle hot crusing ir 35 psi yes thats great pressure , im thinking of an oil cooler cause temps out hear can get as high as 115 average is 100 in the summer time so i think its cheap insurans to put one on cheapest iv fond so far is 200 bucks

All lifters can have problems with the bearings after putting many miles on them, frequency of oil changes, incorrectly adjusted pushrods, etc. I've only had two lifters fail because of the bearings, and this includes several Harleys I've owned over many years. Both had a LOT of miles on them, but I was still able to get home. One was a 1976 Sportster with solids. The pushrod loosened up and beat the heck out of the bearings, causing them to fail. The other was on my EVO and that lifter had over 40k on it, so it was bound to fail soon anyway. I also ride my bikes very hard, so they take more of a beating than most riders put on their machines.
