Air Bag issues fitting Bull Bars

[Laurie 123]

I have been told that if one was to fit a bull Bar to Disco 3 there would be a danger of improper installation, where'as the Air Bags could be affected. Any one know about this?

Not true or else ARB and OL wouldn't engineer and produce them. A home or custom built bar possibly but who wants to be the guinea pig.

So the thousands of D3s out there with bullbars have issues - just think it through for a minute.

As long as the D3 bar has the D3 compliance sticker/plate on it then there are no issues.

Follow the instruction from the supplier of an approved front bar...all should be good

[gavinquinn]

Where would the compliance plate be?

[donh54]

There should be a visible plate or sticker on the bar stating what vehicle it is compliant with

mmm yeah well this is information given to me by RJ motors in Katherine Says if not installed correctly can trigger air bags .Think he is after a bit of business. hehehe

On ARB bars its on the inside lh side.

I think the RJ Motors man is having it on.

My understanding is that bull bar attachment could not possibly ignite air bags as they are set off via 'decelarometers' which I think are mounted under the centre console in the D3.

The main reason bull bars have to be designed properly is so that the 'crush cans' are still operational as the first point of collapse.

The bit in bold is correct.

If you decide to substitute nuts/bolts for different spec ones, or modify a bar designed for a different vehicle, then there is a possibility the airbags could trigger when not required or not be triggered when they are required.

Companies like ARB, OL, TJM test their bars to ensure correct operation of the vehicle airbags.

So if you fit an ARB D3 bullbar to a D3 using the supplied hardware/nuts/bolts and fit it in accordance to the ARB fitting instructions you’ll have no issues.

Can you explain this further please. How can substituting a nut or bolt cause an air bag to go off?

Say the correct bolt is a 10.9 and you fit a 4.6, the lower grade bolt could shear affecting the way the vehicle senses the crash impact, possibly altering when the airbags are triggered. The same could apply if the incorrect diameter bolts are fitted.

The lines of ARB, OL, TJM etc specify the bolt sizes and strengths for a reason.
