From memory, I cannot remember replacing a shock absorber or road spring on a 400 due to wear. They are good reliable units.
As far as upgrading the suspension, I've no experience of it on 400's
Perhaps the ZS springs/shocks would carry over? I don't see why not?
That way, you be assured of no fitting problems
