does anyone have one and who makes it?

 

Contact Denton in CA. Sorry, not sure of the phone number. I am currently trying to put together an anti-vibe stem for a yfz450, and have ordered a 450 stabilizer, but haven't gotten it yet. The stem is the same basic dimensions as the grizzly's, but is 2 inches longer. I am going to compensate with shorter height bars.

Can you tell a little more about your engine mods and a-arms?
