I want to replace the lifters on my '09 Ultra to see if it reduces some of the valve train noise. There seem to be many choices out there and I was wondering if some of you could offer opinions on which lifters seem to be the best ones.

 

It is highly unlikely that replacing your lifters will reduce valve train noise. The HD lifters are about as good as it gets. I reduced the noise on my bike by returning to dino oil.

 

You could also try the baisley performance bypass spring lmr-002. That will help reduce some of your valve train noise.
