New Warn Semi-Hidden Winch Kit bumpers

[Jetboy]

There are no airbag sensors up there. So IMO every bumper is airbag compatible. Other countries have more specific rules like having to actually crash test them to get the approval sticker.

Pricing!?:shocked:

Curious as well. Toyota needs some love from companies that don't have months-long lead time.

I like it, wonder if it will be available without the goofy 2" tube.

Its not where the sensors are, its about energy absorption. ARB designs and tests for this, others do not due to the cost.

So why couldn't this (or the other XYZ brands) work on the '10 - '13s? I'm assuming there are necessary modifications to the giant plastic "bumper skin" on either. Is the width of the "grill opening" so to speak different? I'm assuming the frame, and it's mount points are the same. Or is there a structural change behind the updated facade I'm not aware of? I've got a '10 Trail that is about to become an extra vehicle, and I'm putting a build plan together.

The best I can gather is there are subtle differences between the 3 lower nose covers (SR5, Limited, Trail) so a one size fits all wouldn't look correct except on one of them. The only prototype that was ever made was for a 2012 Trail IIRC. SSO found out about the differences during that build and since they have had several other more promising projects come up, that one has been put on the back burner.

The more pressing question for me: Why doesn't anyone design them to put the fairlead up higher? Most of these put it in a low spot where it's easy to damage the winch rope by pinching on a rock. I know most people don't use the winch ever anyway - but some do. I've beat the piss out of my front bumper. And it should be easy enough if you're creative with the design to simply build it so the winch mounts upside down in the exact same physical space, but then and the fairlead is about 4 inches higher and will fit on the flat face rather than cut into the lower face. That's how I'd design one.

The best answer I can give for this is the winch mounting plate is across the same axis as the frame horns and where the original bumper was located. Keeping the winch directly between the 2 frame hard points prevents undo torsional stress on those mounting points that a higher mounted winch might cause. The larger full size bumpers may have additional bracing to support the higher profile, allowing for a higher winch location. The lo-pro's are pretty much stuck with only the frame horns where the original bumper was mounted. At least that's my story and I'm sticking to it. :yo:

Believe me I have the same concern as you ref damaging the rope. I have in fact stuffed mud into that fairlead more than once. But it is an acceptable trade off for me who wanted to keep the original nose profile as much as possible.

Then why call it airbag compatible? It no relationship with the airbags.

it's related to the airbag because when you have no energy absorption it makes the impact harder (higher g-force)

here is a good explanation:
https://www.arb.com.au/ask-arb-air-bag-compatibility/

[...]
The air bag triggering system is designed to work in harmony with the frontal crush characteristics of a vehicle. These frontal crush characteristics include the design of the bumper assembly, its mounting system, and other components of the vehicle.

On 4×4 vehicles with independent ladder chassis, the manufacturers often also add ‘sacrificial crush sections’ to the front of the chassis members to ensure that minor impacts (such as hitting a kangaroo) are not read by air bag sensors as major impacts, prematurely deploying the air bag(s).

Such premature triggering of the air bag is potentially quite dangerous, and may in fact cause a more severe accident or an injury that would otherwise have not occurred. Likewise, an air bag deploying later than intended by the
manufacturer could also be dangerous.
[...]

[...]
Monash University’s Department of Engineering was contracted by ARB on this project for some years, and their expertise and testing facilities have been used to evaluate, test and approve ARB bars for air bag vehicles.

The essential design criteria ARB uses to ensure compatibility, is to evaluate the standard vehicle’s frontal crush characteristics, and where necessary to duplicate these characteristics as part of the design of the bar and its mounting system. This results in a design which when correctly installed, ensures that there is no change made to the way the vehicle behaves in a collision, and hence there is no change made to the way the air bags deploy.

Just pre-ordered one. We'll see how it goes

 

[Jetboy]

The implication that air bags would not function properly with other bumpers is nonsense. There is a very small window where the crumple zone of the arb bumpers would have any measurable difference. There is little crumple zone in the oem Toyota bumper. It takes place in the frame horns.

 

[e60ral]

They may function too easy with a steel bumper, because of the increased deceleration, ARB is only company that tests to make sure it doesn't impact airbag performance

 

[wfo9]

Airbags still function..with a winch/plate bumper. There is just more force transferred to the cabin.. so they go off easier. It's not really an airbag thing, but an energy transfer thing. Airbags should go off with the same amount of force... it's just that the force will be higher with a hidden winch or plate bumper with all else being equal. There is basically a shock absorber removed.

Umm... Not true... No airbag deployment. And there was no frame horn damage. (just about $6K of OEM body parts, paint and labor)

 

[83Mule]

Good God People!......If I was that paranoid about safety I'd be rollin' a hideous VOLVO! If you like the Warn, buy it! It can't be any more ''Scary'' than the other 3 options of this style and the Price is excellent.:biggrin1:

Pics of your inner bumper? (that's what we're talking about - not the plastic cover, the plastic has no value at all in impact resistance). Normally the aluminum bumper must have failed if whatever you hit caused damage the hood like that. Hard to tell though. If you hit something taller than the inner bumper it might have just missed it entirely. Kinda looks like that's what happened here. Seems hard to see how you can collapse the front aluminum bumper and not set off the airbags.

Do you think something different would have happened had you used a SSO bumper as compared to a Warn bumper. That's really the only question that matters. Is ARB's claim that its bumper is SRS compatible meaningful?

To give you an example:

Note that the frame collapsed and the bumper didn't. So... umm... true?

I know this is a Warn Bumper, but i wonder how it could be modified for a smittybuilt winch.....

If you want a Smittybilt why get the Warn bumper? This bumper appears to be almost identical to my SSO and the Smittybilt works with it. Prices are comparable.

I personally wouldn't want those two big holes in the front of the bumper to funnel dirt, water, road grime, etc. onto the winch.

It should just bolt in. Basically all small winches 8-1200lb have the same mount pattern and same design. They're all interchangeable. The only ones that won't fit are the oddballs like the 8274 and the powerplant that has a compressor built in. They're just physically too big.
