Recently installed a set of Jim's lifters in my Ultima 120" motor , all 4 destroyed themselves in less than 500 miles !! Roller pins cam lose and made a hell of a racket ! Took out the lifter blocks and cam when the inner lifter stopped rolling on the cam and galled it all up ! All I am saying is save your $$$$ they are not worth $90 each ! Total junk ! I would go with S&S . just my 2 cents .

 

That's been a known issue. +1 on the S&S. Sorry!

 

This is interesting and doesn't necessarily apply to the OP's issue, but I just looked on the S&S website and I'm not finding any lifters (tappets) for Twin-Cams. In fact, if I enter the part number of the S&S lifters (330-0175 S&S Premium Tappet Set) I installed in my '14 Limited back in 2016, they're not listed. It looks like they provide them with some of the kits, but not separately. Hmm...

 

"The S&S Cycle Precision Tappets replace both our standard as well as premium lifters for big twins M8 and late Sportster® applications"

Yeah, I saw those, but I have to wonder is/was there anything wrong with the premium tappets that I have in my bike?

Edit - Sorry for going off-topic.

 

I just ordered the S&S 330-0718 lifters from Dennis Kirk. They had them ready for pick up by USPS within a few hours. And they are shipping to California.

 

I have the same ones in my bike and they have performed flawlessly.

 

On my build I installed all S&S products. Great customer service and products. Sorry to hear about your troubles man. At least you are safe to write about it. Stay safe and stay in the wind man.

 

NEVER install a Jims lifter in anything. Personally seen dozens fail. Heres the latest. 2 of the 4 failed the same way. This set only had maybe 5k miles on them as you guessed it the previously installed jims lifters failed as well.

 

JIM lifters are no better than Harley OEM or SE lifters. JMHO.

I have GMR lifters which have been flawless, when the time comes for new ones Johnson hydraulic lifters.

EDIT: meant Hylift Johnson Lifters.
