Only four bolts on a winch?

OK, so I'm still new to the wrangler. I just bought a 12' a month ago. I have since purchased a Elite Warn front bumper and the Warn 8000lb winch. I just installed them the other day and I'm surprised that only four bolts hold the winch on. 4 bolts will hold 8000 lbs? Just does not seem like enough. I could understand if it were mounted with the "legs" in the forward position like some applications. Just thinking out loud. Anybody ever had the bolts break?

Alot of things would break before those bolts do.

I have run Warns for years. M12k, M8K, and a few others. The 4 mounting bolts have never given out. They thread far enough into the cast ends of the winch housing, they are not going anywhere. You need to make sure you are mounting it to a strong, frame mounted sub-structure. I have seen those fail.

I have a 2007 GMC 2500, Diesel crew cab. It was driven the wrong way on the side of a mountain and the only thing that stopped it from rolling about 300 feet was the trees that the front end ran into. I have a 12,000 lb winch on a cradle, with a front receiver and wired to both the front and back.

Ok, so the point I'm getting at is that I used that winch to pull the truck back up onto the roadway, alternating from the front to the rear mount, pulling the truck sideways. With those same 4 bolts you mentioned....8,000 lb truck....
Believe me when I tell you it will work.

The quick answer, as has been stated, is "yes".

But, to give a little more context ...

Winch mounting bolts see primarily single shear loads (as opposed to tensile 'load' like a D-ring). Considering one 'grade 5, 3/8" bolt' (typically used on Warn's 8k winches) has a single shear strength/capability of 8280 lbs and that you have 4 of them ... then, yes, I'd say 4 is plenty.

If one swapped out the grade 5s to grade 8, then you're looking at a shear of 10,050lbs.

That said, I'd have to ask 'what's the point?'. Even with the grade 5s, you're going to have cables breaking before the bolts shear (assuming the bolts are torqued correctly ).
