This isn’t stock, anyone identify this

I forgot Erson. I often wondered if one company made them all and the companies just put their name on the box. Just curious. The aftermarket ones all had the lock nut. The interference fit adjusters on the stock ones work well. A new adjuster usually takes care of any loose issues.

Probably. There are not that many companies out there who can extrude a rocker or forge one. So they probably have 2 or 3 options to get the stuff made.

And maybe not even that many today.

Of course, even thought the same manufacturer may make rockers for several companies, I would think that each company would have its own design and geometry and such. Or maybe they just copy others stuff and sell it.
