Review on 3L3Z6564A 24X Rocker Arm Set For 2005-2014 Fo-Rd Mustang GT Explorer Expedition F150 F250 F350 F450 F550 by Marvin Breezy

I'm in shock, just spent a month building a new motor, rebuilding heads etc. In a week three of these Lifters have failed. They fell apart completely. What an absolute nightmare. I even use a large volume high pressure oil pump. It's just Chinese junk. It sucks, every time I stop I have to listen to the motor before turning it off so I know if another lift has failed.
