Adding bolts may not be a solution. You could make it 8, 10, or 12 and then you have frame horns like swiss cheese, and just as strong. There can also be a lot of torsional stress and upwards stress from hitting rocks with the bumper. Which I have done a fair amount.


As you can see, I even bent my bumper at the hole where you can reach in to move the cluch on the winch. Mine has held up fine, and I have used the winch many times as well as the tow points. Following torque specs is important. when you torque a bolt, you are stretching it to a point, when you over torque it you strech it too much and weaken it.

Sometimes, things just break on the trails.
