I contacted the manufacturer and currently the only replacement remote available is the Replacement Wired Remote Control with 12' Cable # SW93GR. Which is the 12' version. There currently is not a 30' or wireless option available.
If you wanted to upgrade your winch to a winch with a wireless remote you could get the ComeUp Cub ATV Winch w/ Mounting Plate # CU123933 which would use the ComeUp Wireless Remote Control # CU881286 to control the winch wirelessly. view full answer...
Most Superwinch winches use the standard 10 x 4-1/2 inch or the 6-1/2 x 4-1/2 inch bolt pattern. If the mounting bolt pattern on your winch is compatible, you can use the Curt # C31010 receiver mount. The winch would install using 1/2 inch hardware which isn't included. A pin and clip like part # PC3 is also sold separately. view full answer...
