Just curious will the 400ex a arms fit on a 300ex... I mean everything, I know they will attach to the frame but what about the spindles.... And every thing else

 

why don't you just use the 400ex spindles and the tires and rims if the 300ex ones don't fit.

 

well i have the 400ex shock conversion already and there is a set of 400ex a arms on sale on e bay for like 30 bucks... I didnt want to spend much more than that haha .... and the set of a arms doesnt come with spindles, so i didnt want to get the a arms and not be able to use them...

 

The 300ex spindles bolt to the 400ex A-arms. You will need 400ex tie rods, but the ends are the same. Brake lines will get tight but they will reach safely.
