Brushguards have no effect on approach but, that winch mount sure does. At the bottom of steep downhills, that winch becomes a mud-shovel. (they also like to snag your garage door!)
This "shelf" type of winch mount can bend the frame rails if you are pulling at extreme downward or upward angles. Some guys weld thicker plates to the ends of the frame rails to try to combat this problem. IMO...that's sort of a band-aid. The real reason the frame bends is because it only uses the (4) mounting bolts at the front of the bumper. These four bolts are located in the same horizontal plane and because of this, they don't add any triangulation to the mounting stresses. Also because it sticks way out front...the shelf itself creates a cantilever situation. It acts like a giant breaker-bar on the front frame rails. Even though I'm not a big fan of these mounts...they certainly have their place. They are cheap...easy to install...and it beats calling a tow truck! If you are on a tight budget, and you need a winch...they're a great alternative. Another nice thing is: the winch is up high, and fully exposed so you can use and maintain it.
Most other winch mounts (actual replacement bumpers) utilize all (8) mounting bolts, (four more located further back on the frame). This triangulates the mounting and makes for a much stiffer winch mount. Also mounting the winch further rearward past the ends of the frame rails will greatly reduce the cantilever forces. They are more money but, I have zero issues hanging an H3 completely off the ground by the winch...if a THORparts, DOI, or ARB bumper is used. But I would never try that with a shelf-type mount, and I would be very hesitant to try it with the BA. While its true, the BA uses all (8) mounting points...but its built from very thin metal with questionable Chinese welds. There are choices out there...for every budget and every need.
Amrg... I have THORparts in Guam, Australia, Canada, Puerto Rico, United Arab Emirates, Russia, and Borneo. I'm sure I can get you one via UPS or Fed-Ex. The complete front bumper (with pods & grille) weighs only 110lbs. and ships in a 48"X12"X24" box.
