will a yfz 450 rear shock work

Yeah I think you may have to drill a new hole for the swinger mount ( make it bigger or something ) But like said it jacks your rear end way up.

Yes you have to cut the lower mount and drill new mounting holes. Well from what I read on here about it. I actually used the search function LOL:D

Djack has one on on his Blaster. I was just asking the same thing in the chat box LOL. I found a guy on eBay that has a bunch of 04-05 YFZ450 rears for 75.00.
