Replace it.

@MongooseGA has the killer idea - replace the sub-bumper with structural steel and hide that and the winch mount with the O.E. bumper. I did this years ago with a Jeep Grand Wagoneer. I loved the look of the O.E. front end, but wanted to mount a Warn 8274 winch. We built the sub-bumper and mount, slotted the O.E. aluminum bumper and slipped it over the winch mount. The winch looked like it just stuck to the front of the Jeep.

This is the point in the thread when someone who's actually fabricated bumpers for a 100 will chime in tell me why ^that^ won't work. And... I'll have to agree. I built a lot of Jeeps. I have only put parts on the 100. ;-)

Ooh I like that idea as well. I personally like the look of the front bumper and never felt I need an aftermarket bumper if all I needed it for was for approach clearance. Most folks who have them nowadays only use them for the looks anyways so it didn't make sense to me.
 
It looks fine as is to be honest. Plus you don’t wanna cut off too much (you found the sweet spot), might be a negative affect on the MPG gain if you cut off any extra.
If you do as much as crack a window in a 100 series your MPG is gonna drop. o_O I gave up on that battle years ago.

I have a soft spot for waggys. Nice!
 
I know there's been some sarcasm about mileage in this thread, but holy cow, that's it? Are you the guy running 20s? What do they weigh??


I'm on 285/66/18s and believe me the weight of 18d vs 17s or 16s is really overblown. Maybe because I have a led foot? I also drive about 95% streets as opposed to highway. When I drive all hwy miles I get closer to 15 or 16
 
I agree I have used this tread for inspiration too but my buddy did a little more aggressive trim and it turned out quite well in my opinion as well as a winch mount.. View attachment 2951321View attachment 2951322View attachment 2951324View attachment 2951326View attachment 2951327
I think I like this. Need to let it marinate a bit. Like the added lights and black paint for sure. Kind of a cool cheap mod(especially if you are already thinking about a different number in future anyway) . What size tires is he rolling on?

Sorry for the late response but in these pictures I believe he was running a 285/75 with those newer 17s but he has since upgraded to a 35/12.50/17 now..
 
Decided to go ahead and chop it today. I plan to paint the bumper or eventually paint the entire rig and color match the bumper. I’ll probably go with cement gray.

This looks pretty good. What are you guys using to cut? Angle grinder?
An oscillating multitool with a hooked razor blade in the head. Hands down the quickest, cleanest, and easiest way to trim plastic. That was also my easy solution to the rear mud flaps. I know there are products out there to replace them, but just trimming the plastic was super easy and cheap and now I don't have to worry about the rear bumper ripping off. Jig saw to trim the aluminum bumper in the front. I plan to fabricate a hidden winch plate. Overall super pleased with how it looks and hopefully how it performs. I did run a couple selt tapping screws through the bottom holes of the license plate and into the aluminum bilumper to hold the oem plactic in place for now since the cutting removed the mounting brackets. Nice way to save weight and $$.
