'08 vs '12 primary rollers

[MtnMaster]

are the primary rollers from a 2012 the same as an '08? I need a set for this weekend and local dealer only has a set from a '12 and says they're different. I don't see how they could be different other than maybe a different outer diameter like a 1mm oversize or something. Need help asap, don't want to drive 45 mins to the dealer unless I know.

they may be larger. who cares just use them. pins and arms should be same diameter

yup, thats what I thought. Just going to run to the dealer with my old ones and grab them. I'll weigh them and see if there is any difference. PS don't use thunder product aftermarket ones, they only lasted 3 rides and the bushing in the center of each roller is pounded out. Stock ones never wore out on me, tried a set of 1mm oversize and they worked good, but didn't last.

I'm betting it's just a different part #, if they change supplier or material they get a new part#. most important thing to check is sliding and spring cap bushings, if they are at all sloppy you will eat up every thing else in a hurry
