My understanding is it strengthens the a-arm mounts by tying them together. I've got the turnkey gusset but haven't installed it yet. It does' nt look like it would interfere with a winch but I m not positive.
UTV Inc has been asked that by many people. All they come back with is they need pictures. When some are sent they say not good enough.
Wonder how they made their other parts. I don't remember that many pictures being sent.
