I see that now.

Doesn't have anything to do with it. The AB's are set off by deceleration of a moving object (in this case the truck, and the AB sensors being mounted at 2 different places on the truck are going to decelerate at the same speed as the truck). In the case of Ford, at least they used to use a system that used a Gold plated ball bearing that had to pass through a tubular channel that was only about 4-5 thousandths larger in diameter than the ball. And the channel is magnetized so it resists allowing the ball to pass unless there is enough inertia. When the ball overcomes those obstacles it hits 2 contacts at the other end and completes an electrical circuit. Very precise but different auto manufacturers use different trigger systems and decide they want the bags to blow at different speed than another AM. Then a given AM may change their theory as time goes on. All I can say is, there should have been NO DELAY as the OP posted. I can't say those things don't happen, but the systems rarely fail to do exactly what they are supposed to do.

Dude, you wrote that at 4 AM. How are you even functioning enough to explain that with such detail? Much less write it all down in complete sentences?

x2. There shouldn't be a delay. Even if there was it would have affected both airbags.

I personally plan to AVOID any large or even small concrete chunks in the road.Its those things that appear in the road that you CAN'T avoid that scares ME.If you fail to plan, you plan to fail.I plan on surviving , and I lost faith in the structural integrety of those trucks.2010 tests out yet ?

Bingo! I'm up kinda late, but not THAT LATE!
We'll see what this comes up at. It's 2:03 AM here and I'm ready to hit the sack.

AMEN to that. While the NBS trucks are more "engineered" I will say that after being involved in crashes with a '74, '86, '99 and '01 F150 there is nothing better than sheer MASS. I will NEVER put my body into a little econo-box car again. I like it when my 5700 pound truck moves the other car into the next lane, totals it in damage and I drive away with hardly a scratch.

Give me a body on frame truck any day

There still seems to some unanswered questions.Does having an aftermarket brushguard on your truck make a difference with airbag deployment timing ? Does it affect passenger safety ? How about winches ? Snow plows ? Seems we have opposing opinions..Experts help ? Makes me wonder

No it does not. Airbags are triggered by G force of rapid deceleration and not by striking an object.

It will affect the safety of the passenger you hit.

Same as above.

That must be were the desingers decided on the shape of the NBS reg cab.

Doors are a structural part of the extended cabs for that reason. And for the test they removed the doors. Lets remove the core support next and see how the truck fairs....

I had a 35 mph offset crash with my truck and the damage wasnt nearly as severe as that video depicts....

Exactly. It's not really hard to comprehend at all.

Air bag systems on the 97-03 trucks have three sensors, two have to be "triggered" to cause a deployment of the bags.

Two crash sensors (located on the core support) Left and Right
And a safing sensor (G force based on deceleration)

Having a brush guard on the front increases deceleration (less crumple zone effectiveness) and decreases your crash sensor sensitivity and reaction time. And makes you more likely to bend the frame rail since the bumper brackets can't bend, and the crumple zone on the frame can't crush like it are supposed to..... No thanks.
