2 lifter fails in less than 2 weeks 6 hrs labor and materials wasted.

I replaced all 8 lifters on my driver side head. Took a lot of time to figure out that one of the new lifters delivered was bad (on 7). I replaced the bad one since I had 4 leftover. Put it all back together again to find out another one of the lifters in the set failed as well (on 1). Maybe I will get lucky with one of the 3 leftover. Good thing it doesn’t take much time to pull a head. At this point, I wouldn’t buy any other parts from this company if this is how they roll.

These are horrible. I install them in my suburban. Had less than 10 miles on them and they grenade it in my engine.Update- they did give me a refund for the parts. But said that they wouldn’t help with the extra cost I had to pay for another set of lifters to be installed.

I've been a mechanic for over 40 years. These lifters are very poorly made. First they drain down when you shut down the engine. Then three collapsed after fifteen minutes of running. Such a waste of time to replace them.

This product is junk Iv had these lifters fell 2 times in the shop again getting them took out to be replaced
