like it says..
I decided to compare the OEM lifters I took out of my twin cam, my 2013 to the woods alpha lifters and this is what I found..


Woods is on the right OEM on the left..


I got to tell you I know that top line / iliff Johnson makes the lifters for Bob Woods however I was not impressed with them at all.. I thought the spring for the plunger was weaker and the cup which is separate from the plunger is wicked loose in the plunger. . Bose plungers fit the lifter with pretty much the same amount of clearance.. I personally feel that the woods alpha lifters do not deliver as much oil to the top end as the OEMs You'll see all my measurements below or above whatever.. The rollers and the needle bearings appear to be identical..
Take note of the measurement of each plunger and you will see that the woods alpha has a larger diameter piston than the OEM which I believe takes too much away from the sidewall of the lifter body.. Not only that even though the springs wire size measures almost identical the OEMs have a much stronger compression on the plunger than the woods. The Woods were like hardly anything..
Now if you take a look at the diameter I measured with my micrometer on the plunger bodU OEM I got .6155.... Is that the older style b lifters or the newer style C lifters?
I did not disassemble the S&S premiums that I have so I have no idea what the measurements are overall for those lifters compared to the OEM or the Woods... However what I do know is that the S&S are nice and quiet and the woods failed on me.. They were so noisy It was hard to believe and I wasn't expecting that because even in their advertisement they say Cam lift does not matter as compared to DMH where they're only good to 0.600"...
I will be trying to get some type of replacement from Hilift Johnson, these lifters failed with this new cam the T-mann 660ps2 in 150 miles and they're just a year old it shouldn't have failed but they did...
If you take a close look at the picture it even looks like the spring for the woods lifter on the right actually bent...
Let's hear your opinions always willing to learn something new. But I think the Woods lifters suck...

 

I can't speak to the Wood lifters as I've never used them. What I pretty much have deduced from listening to folks over the years is it's about a 50 / 50 split over loving them or hating them.

As far as OEM lifters:
-99 lifters I believe were made by Johnson Lifters, (not Hylift) and were the larger diameter internal piston.
-99A lifters I'm not sure if they were made by Johnson Lifters, (not Hylift) but they also were the larger diameter internal piston.
-99B lifters were made by Delphi. They are considered the best lifters that HD ever used in the Twin Cam. I bought up several sets before they went extinct. I think they're fantastic. They have the smaller diameter internal piston.
-99C lifters are the current HD lifter, were outsourced to Mexico I believe, and are considered poor quality lifters for performance use. I would change them out of a bike I owned, stock or not. These are also the small diameter internal piston.

As far as spring shape, oil port dimensions, those are engineered sizes to mate with entire lifter function. I wouldn't read anything into the sizes. A light weight coil spring at free stand is not that uncommon to have an arc to the shape. The new Wood lifters use tiny oil ports and the lifters are supposed to work very well. To early to determine as I don't know how many are in the field, I've heard nothing good or bad about them. My understanding is Bob Wood has an agreement with Hylift on the design of the new lifters, and they won't market them on their own.

What I know works:
Larry's 2313SE and 2313SEL (with limiters) lifters. They hold up well and are quiet.
S&S Premium lifters work great. They are no longer made and sold by S&S. They have one lifter option, and I believe it's really their old standard lifters.
-99B lifters are top of the food chain, but also are unobtanium.
Feuling are supposed to be good lifters, I have personably never used them.

 

Those look like 99C. Looks like the snap rings. Compare the pin ends to the Woods. Woods have the swaged pins. Don't use them..

Heck install limiters in the Woods. Bottom is a 99c that broke on a 107 TC all bore with DM598 cam.

 

The only lifters I have ever had that failed were HD. Replaced failed one with after market never replace any of them. I am sure others have failed just has not happened to me.
Pulled the factory one on my 114 at 8K they were bad replaced with S&S 35 K going strong.

 

what is an obtainable lifter to go with now? I had fueling but bike didn't start after installing them because I didn't use adjustable pushrods , but feeling said they could have worked with stock push rods. I bought screaming eagle lifters but didn't install them yet, are these good?

 

In all honesty, for the money I would get Johnson Hylift from Larry's Motorcycle and Machine. The 2313SE are great lifters. I've used them and have zero bad to say about them. I also know Larry is honest and knowledgeable. He's ported a few sets of heads for me and they perform really well.

Had an S&S fail on me. That's it, fail once, I'm done

 

just checked his site, I have the wood tw6 cam stock springs. would I need the 2313se or the 2313 would suffice?

 

If I'm buying them, 2313 for stock valve train and 2313SE for performance valve train.

2313 should hold up fine. 2313SE gives more insurance with slow leak down, and oil ports for the roller pins. To me the 2313SE price isn't high enough of a difference to use the 2313.

 

I did install the S&S I had in the shelf..I put them in new 8k miles ago.. Only pulled them because of the 110 kit from Fuel Moto came with the Woods so I though it's give it a try.. Never again... There is nothing that impressed me about the Woods lifters.. By what I've been hearing the Alpha lifters are the older style that you can't get any more.. He now has a model called Platinum.. Must be the other ones weren't that good..
