Put a tack weld on the bottom of the bolts where the nuts are tightened at. It at least keeps the honest people honest, but i still recommend keeping your reciept for insurance purposes. Daniel
Too damn hard to grind it off when you need to remove the winch. A quick tack on one or two bolts is all you need, and it won't hurt anything. All four bolts don't need to be tacked, if one isn't removable they can't steel your winch. If you call and ask Warn how to secure the winch, they will tell you to tack one of the bolts.....I had called them.
