The Superwinch LT2000 winch has a 50 foot long wire rope with a 5/32 inch diameter so for a replacement the best I can currently offer is the # FWC7500100 which is 7/32 and 50 foot and you'd be set. There's no way to convert the winch to a synthetic rope.
I attached a picture that covers how the replacement is done as well. view full answer...
What you'll need to do is measure your current springs without the weight of the trailer on them and we'll be able to set you up with the springs you'd need. We most likely have a fit that would work well but here are the options we have:
# e54SR which is 25-1/8 inches long
# SP-210275 which is 27 inches long
# e59SR which is 23-1/8 inches long view full answer...
