Need Help with Deer guard front bumper design

[bc1]

Hello guys. Working on a design for Deer guard on the front bumper of my 2025 lightning flash with front sensors, camera, and adaptive cruise. I was reading Martin's thread about tow hooks on the rear bumper and noticed he looked at the front end from an engineering point of view. I am just wondering if he or anyone else has idea on how to attach a front deer guard? I'm figuring on 3/8" to 1/2" thick steel and drilling & bolting it to the frame with either 1/2", 5/8", or 3/4" bolts to bolt it up. Will also have some type of gussets on the corners going back to the frame and drilled and bolted there. It looks like the bumper cover is mostly vinyl so I'll probably just chisel out enough to fit the mounts through the cover and front trim.

Having totaled out a 2021 Subaru Forester hitting a deer head on driving to the farm at night, I am designing a deer proof front deer guard made from 1/4" or possibly 3/16" steel with the final design and style to be worked out. Most of what is out there are brush guards and may take care of a fawn if hit square on in the middle but any size deer hit on the corners is going to buckle that round tube back into the fenders and headlights. My designs have to allow for the frunk, adaptive cruise control device in front, and the front sensors. Between the price of new steel and my welder I can already do it cheaper than what they sell for anyway. I drive at night a lot on two lanes in deer country and the rut is just starting. I hit a coyote last spring with the Prius on the right front fender and it was 6000 in damages. There is just enough traffic out that most of the driving is on dims.

Right now I am looking at 4" steel square tube, 4"x6" rectangular tube on edge, and 3" square steel tube for cross pieces and about 4 uprights. Maybe some 3" round tube as some filler of lighter weight. The front would angle back at the same points the factory bumper does. Probably have a U shape in the front for the Frunk that is pinned and would fold down. Typical full sized whitetail deer is up to 250# and the body starts at 18" and can be up to 36" at the shoulder. I'm thinking a bar below the tow hooks, above the sensors & below the lights, and a third above the lights. I'm not quite to the point of a Kenworth west coast bumper some of the local bull haulers use but close. Down low the rectangular tubing would have more strength and maybe up high could be something round as long as it is all tied together and perhaps tapered to the rear somewhat. Most of the deer guards on the road now that have two front upright guards inside of each headlight are just made of 1/8" thick steel.

So any help is appreciate. I know it will be heavy and I don't really like those Ranchhand's and other bumpers that replace the front bumper and they don't make them for a Lightning anyway. Thank you.

I have made several front receiver hitches. I use a clamping setup on the front tow hooks. You would need additional mounting points up higher also I would think. Not sure where to do that.

I also think the front tow loops are a good place to start.

FYI I have looked at the inside of my Lightning's front wall of the frunk, for an unrelated project. To me it looks that there's significant strength designed into the top half of that inner front wall... just an idea. Obviously, I'm not suggesting to cut into it from the outside, but it just might bear some weight as a brace, with careful design.

Yeah those of us who have had an encounter with a deer are not likely to forget it. I wiped out two deer on two different roads during my Army time in Germany... the BMW showed it.

Thanks. I took a screen shot from the guy who did a video from adding adaptive cruise control to his lightning. This shows the front end with the bumper stripped off. Might be room to create some type of insert into the frame opening above the tow hook. I'll see if I can post the picture.

Would it be simpler to just add a snow plow? And if snow is not a concern where you drive, perhaps you could cut holes in the blade for headlights, etc. with an angle grinder.

Eh, having hit two 100 pound deer at 45 mph (separately..). Each one did $4k+ damage. But I really worry about those 550-1200 pound elk… which would likely total a F150 if hit head on at 55 mph. My only solution are extremely bright driving lights (all past rigs had Hellas). Or stay off the throttle wear the forest is dense & tight to the highway. Can’t think of a guard that would help other than a long nose Kenworth or Peterbuilt.
