I saw an X12 arm for sale that said X12+ on the tag. Does anyone know what the (+) means?

Maybe higher timing?

I don't think it would of been a Koford arm.

I don't remember a tag like that in the 19 years I worked there.

I may be incorrect but I think that means it is high timed. Anyone else have any info?

How many would you like?

Mura X12 arms from the 1990s were labeled X12 and had about 34 degrees timing. When they started to time the arms at 38 to 42 the tags were marked X12+.
