Current Jesel info from their web site:

Talking to Rob Remesi at PRI in 2019, he said other "competitors" were eating into their market and aggressively pushing the bushing style lifters. Jesel reluctantly began offering them to retain and grow their business. They clearly favor the needle bearing style however. In the video he stresses that ALL THE COMPONENTS are manufactured IN HOUSE at their plant in NJ. That includes the needle bearings, the heart of a lifter or rocker arm.
