warn 9.5 ti winch

hi all i am going to change the wire rope and was woundering if it is possible to put 38 meaters 125 feet of synthetic 11 mm rope on the spool ?

Check the manual for their specification. The chances are it will fit even if it says it won't but.... here's the thing. If you over fill a winch drum you will have to be very very careful not to bird nest when winching. If you cannot pull in a dead straight line and the cable or rope builds up on one side of the drum you have a very real chance of slicing through it. I have an extra long cable on my truck winch but although it is a godsend when I need it. It is a right pain when I don't. (which is far more often). You also have to remember that your winch loses power the more layers of cable/rope you use due to altering the gearing.
