It looks like the Warn 2.5 ci was a 2500-lb capacity winch, so you can use the Bulldog # BDW15002 as a replacement for that winch and get a slight upgrade in capacity. This winch will mount to the mounting plate # BDW15108 which is designed for the 2 bolt mounting plate on the BDW15002.
If you have a 4 bolt mounting plate on your Arctic Cat 400 you'll want to use the Bulldog # BDW15006 which has a 2500-lb capacity. I've also linked some video reviews on those winches, as well as the rest... view full answer...
