Yes, but you will need to modify the bushings to make them work. The travel and length are the same or very close.

The length is slightly different. Before I sold my stock Arvins, a friend of mine put them on his EX. They were slightly longer if I remember but worked fine. He put his bushings and all in them and hooked them up.

I knew they were real close. When I spoke to Elka they stated you could switch the shocks between them, but the bushings were different. the only shock that wasn't recommended for the change was the Z400 it apparently has a longer shaft.
