I've sold a few sets of these over the years, never an issue before.
I felt these were really the go-to lifter for this application, street/strip 505 with about .650 lift, which is why I recommended them in the first place.

Efidart, do you know if yours have the oil feeds to the bushings like the ones in the pics from HardcoreB?
