400ex a arms

i was wondering how much work it is to install 400ex a arms on a 300ex and is it worth it. also what parts do i need and is there any other good setups like this one for cheap? thanks

they bolt right up u will also need new tierods...but it will also make ur quad sit lower so u might have too get a diff shock set up.. i dont think u can use 400ex shocks either they are too lonf u would need to make diff mounts,or buy the ones off ebay...
