My DON bumper is modified with a stinger and to fit a Warn 8274 winch. I had to drill my own holes, no big deal. I knocked off the welded in nuts that hold the stock bumper on and drilled out the holes to fit 1/2in grade 8 bolts. I have 2 per side. I have not had any problems winching with it with either the 8274 or a X8000i. Both are rated at 8000lbs, but the 8274 will out pull the 8000i. I have winched hard enough to stop the 8000i and then hook up a snatch block to pull a Jeep out. I have also winched to where the 8274 was going real slow. I still do want to add some supports to the frame rails, just in case.

The ARB is probably a stronger bumper, but the DON is great, and half the price. I guess it is up to you which one you like better.
