Sorry Will, have to laugh, all that time and money on a WARN, from super winch and you're still having rope issue's?
ME and my wire keep chugging along yr after yr of plowing snow HAHA! sure once in a while it snaps, and takes me mere seconds to fix and back going again? and a whopping 10 bucks for 50 ft of new line LOL
BUt I do think that a roller fairlead will help you a lot, they just have less friction on things being able to roll
another things, and again , this is a ??? fix, if your going to replace the line, WHY not just buy line for a heaver app;application/diameter, this will sure add more life to things, as it will handle more stress and be stronger , you will have to narrow the end to fit on the spool, and then you WON"T get as many feet on the spool, but its can be done and can make for a LOT less likely line to snap on you, will kill your motor before breaking maybe LOL
I know yrs back when I got my first atv winch, it had super thin wire rope on it and when time came to replace I went up a size or two (forget exact sizes) and never had any issue, winch is still working 17 yrs later?
as for sleeve's
like said above, you should be able to a fix it to stay put, a simple idea from me is to use some electrical tape to hold the ends in place, it should still stay flexible enough to wrap on the spool then, and yet still hold in place!
ALso, HOW did your angle mod work if you got to plow any snow with it??
