New lifters
I ordered the lifters a 1984-1999 harley Davidson softail custom. The return window closed on May 23. I just attempted to install them , but the lifters didn't fit. It turns out the lifters were for a twin cam engine. 2000 and later. They also fit the Milwaukee 8 engine. Make sure you get what you ordered before the return window closes.

Good price and seems to be built well , but only time will tell

Poor quality.
The first set I received were for a twin cam so I returned them the second set were correct but I noticed after a couple of rides and as the temperature outside got hotter they began ticking at a idle. I have good oil pressure and I tried to adjust the 2 flats tighter I noticed a slight improvement still has a mild tick. I don’t believe they will last very long. I’m going to order fueling lifters and replace these ones. Maybe if you live in a colder climate they maybe ok I don’t know.
