I have standard works shocks on my 400ex and was wondering if I get new +2+1 a-arms could I still use these same shocks?? Thanks James
If you get +2+1 standard travel arms you should be ok.
ok if I get standard I should be ok but its the long travel a arms that I would need new shocks for?
That is right. Only with the long travel arms do you have to change shocks. ;)
You should probably have them revalved.
It will make your shocks softer because of the leverage of the wider arms.
