A Z-6.0 will get you a 31" DL on a Trykon XL. You will also need to order new strings and cables to complete the new setup. String length will be 58.5",control cable 42.5", and buss cable 39.5".
You could get by with just getting the longer string because the 4.0 string is 1.5 inches too short but it's not too much more expensive to have everything done at once. John
