Push Bar - Is this too much?

[llhoneymoons]

I was thinking about adding these to my truck.

Does anyone have any experience with these, or something similar? I was reading through an older thread and saw some comments about potential issues with the front parking sensors.

Any help is appreciated.

There are a lot to look and consider. I guess it depends on the year truck you have and where the sensors are compared to the bull bar.

These things tend to protect the truck but not the passengers as they don't crumple like the body and frame are designed to do in a frontal crash. I'd do a lot of research to confirm/deny this before bolting one on.

have seen emergency, utility, and other service vehicles with bars; not sure of the year vehicle though.
they may be from 'fleet' sales and didn't have the sensors?
I've heard of sensors being relocated; not sure of the effectiveness thereafter &/or voiding a warranty.

post up what you get before/after pics.
thanks.

Fleet trucks dont get sensors.

You can also move or remove a "conflicted" sensor

Airbags are one thing. The whole front end is designed to crumple in a crash. Unlike your '64 Galaxy with retrofitted airbags.

Please don’t

I can tell you from experience that getting in a somewhat minor crash with a push bar on a vehicle, the push bar will cause more damage than would have happened without it. They are not particularly strong and get crushed into the body quite easily.

 

[gixer2000]

I know certain insurance companies also don't want them on vehicles they insure because they can cause more damage or personal injury. You might wanna check because if your in a front end crash with one they can decide to Not cover the damage. I've already spoken to my insurance agent about this with my Nissan Xterra and was a no go from commerce insurance

What bloodhound said: on the Land Cruiser forum I used to be active on, we called those pushbars and brushguards “damage multipliers” because a minor fender bender that might have only caused a scratch or small plastic dent would actually be made worse by those add-ons because they are relatively flimsy and mounted low so they bend back against the vehicle and actually have been proven to cause more damage. If you want armor, get a proper ARB type steel bumper. I had one on my triple locked cruiser. Somebody makes them for the Expeditions too:

As stated by others, flimsy brush guards cause more damage. Has to be stout and actually have a solid mount (not just 2 little bolts).

We used to fill tube bumpers with water/calcium mix (to keep from freezing, same stuff used in tractor tires) and seal the endcaps with a little silicone. If you ever hit anything the water would blow out the endcaps and help dissipate some of the crash energy.

For purposes of hard and fast blunt impacts, water might as well be a rigid solid

There’s more science to this I think. In Michigan we have big 55 gallon plastic drums filled with water set up like bowling pins in front of some of our bridge abutments on the interstate. The concept works for dispersing energy. They are called impact attenuator barrels. Sometimes they fill them with sand. But the tiny amount of water inside a metal tube bumper can’t be that effective I would think?

If they were filled with just water, I would hate to hit one in the winter.

A 3” diameter tube bumper (which are typically barely 3/32” thick steel) holds a substantial amount of water. The water does actually dissipate energy. Since water can’t be compressed, it is forced to move. So as the water is pressurized by the impact/pressure on the tube it must overcome the plastic end caps and then exit the tube. This is all energy that would have been transferred to the vehicle had the water not been there.

Is it a perfect answer? No. Does it work? In theory. Do I have scientific evidence? Not at the moment but i’m sure somewhere on the interwebs it has been tested.

Would police fleets use them if they were a liability to the drivers? Not on your life.

Ford addresses the issue in their retrofit manual for the Expedition. They mention only that the vehicle may respond differently in accidents. That's very subjective.

To correct one point posted here - Fleet and SSV vehicles have exactly the same airbag and roll sensors in the same places as the rest of Expeditions. The airbag sensors are not affected by a push bar and still react if the occupants are endangered. Unless, of course you drill a hole through the thing or move it.

And yea, a push bar can crumple a hood that would otherwise be missed in a crash. That's a great point.

Many push bars, bull bars grill guards are Chinese junk and just made to look cool. I'd suspect if you want to get any real protection out of a product, look to the American made stuff the police agencies use: Generally Setime, Go Rhino (Mexican), Pro-Gard and Westin.

Wow. This has sparked quite a conversation and provided me with some great information I did not have previously.

The reason I was contemplating this is because a part of my grille is damaged. Neither my wife or I hit anything and we always park in a spot that will minimize damage. The only thing I can think that happened is that one of the neighborhood kids ran into it. If i had the push bar, he would not have damaged the car (FYI - the replacement part, which is just trim, is ~$150). Yes, this is cheaper than the Westin push bar I was thinking of (link in my original post), but I also like the way they look. However, after reading some of the posts, I will have to give it more thought.

Thanks for everyone's input.

Wow looks like a bullet hole.

I have been buying Ford OEM parts for my truck from www.fordpartsgiant.com. The parts are significantly discounted over my local dealer price I saved over $50 over what my dealer wanted on a couple of chrome mirror inserts for side view mirrors.

You might go there and see what they charge for that part.

 

[llhoneymoons]

Thanks for the tip. I will take a look.

Bullets typically leave clean round holes on the surface of soft plastic, paperboard, and animal tissue.
