440Source Solid Roller Lifters

They do NOT need direct oiling if they are needle brg. A sales gimmick. It is an engineering fact that ball & roller brgs survive on minimum lubrication [ think: wheel brgs, U joints ].

I would only buy top brand roller lifters. That is because if they fail, the cost to repair the damage they could cause....will faaaaar outweigh the cost of good versus best quality lifters.
