I WANT TO PUT Z 400 A ARNS ON MY Z 250 AND PUT STOCK Z 400 SHOCKS ON IT WILL IT WORK????

 

Go to the dealer and take your quad with, ask the parts people if they have an a-arm for a 400 in stock, if they do, go see if it matches up with your quads bolt mounts, as far as the shocks are concerend, you would have to do the same thing.
