I put ProRide mounts in my 18 Pro and I think they are better.
Same diamter as 18 but wider and a diffrent compound. But the rubber notches is deeper on the ProRide mounts.
It vibrates a lot more at idle with ProRide mounts
I also bought mounts from Stroker Customs and it was ProRide mounts I got from them.
It wouldn’t surprise me if they were pro ride mounts, they looked identical. The stroker mounts did close the gap that pro ride mounts didn’t but I suppose that could just be manufacturing tolerances.
