Summit Racing lifters

I lost one lifter with the Lunati cam kit.
One day, one lifter did not pump up, bent a pushrod and trashed a rocker arm.
I guess every manufacture has issues.

But was that the micro-trol’s? Lunati has two different lifters. Most cams come with their standard lifters which have the wire retainer. The micro-trols have a snap ring. I’ve had issues with the standard ones bleeding down.
