With some aftermarket ACE bumpers, you might need the winch-to-bumper adapter that comes with the Polaris bumper. If you need the bracket but already have a bumper, you’re not out of luck. The winch mount by Warn can work on older ACE editions, but it mounts your winch upside down. You need to remove the bull bar mount and might need to find/make your own lower piece to hold the brush mount. You can also fabricate an L-bracket of your own to mount your winch. The bottom plate should measure 6 3/4" by 7" while the top plate should be 2" by 7". You can drill the mounting holes in the bottom plate first, mount it on your ACE, then tacked the top plate to it while it is on the machine (making sure to exercise caution and not melt the plastic), marking where the holes should be to mount the brush guard. You’ll want to cut the large box in the center of the bottom plate bigger than the existing box on the winch. Then, of course, you want to weld your gussets on. You can also cut out one bar on the side of your grill to make room for your winch hook. Regardless of how you choose to mount your winch to the ACE bumper, we highly recommend getting the KFI front plate. Even if you have a brush guard, you still might smack a tree or other trailside obstacle and snap your winch motor right off -- and since the factory cover is plastic, you still might worry about rocks with a brush guard.
