Seems as time goes by OEM lifters go up in price like gold. I am curious about the quality of aftermarket lifters from Taiwan and China, such as DNJ or ITM. I ordered a lifter from DNJ and a OEM Nissan lifter for comparison. I will post my findings but I am curious if anyone has experience with DNJ lifters for feedback on long term use. I have worked with Chinese manufactures in the tooling and machining industry and have seen quality improve greatly in some products and lack in others. As our OEM parts diminish eventually will have to resort to aftermarket suppliers for some items, and I want to know which ones we can rely on. OEM is best but sooner or later the time will come.
