Custom bumper vs. Airbag
 
Hey guys, I have a 98 TJ and I'm going to start my custom front bumper build here soon, and I started thinking about the airbag. I will be completely removing the stock front bumper to start from scratch and most likely lowering the winch I have on there a bit. I realize it takes a certain level of impact to set the airbag off (considering I trashed the rear-end of a pontiac G6 without an airbag going off, or a scratch...) but I just don't want to have to worry about an $800 airbag replacement when I'm fiddling around with the front end. Let me know what you think, please!

The bumper is not tied to the airbag in any way. A G force (type) sensor determines when the bag is deployed. The only way you could set off the bag by changing the bumper is if you used a wall to slam it into place.

^^x2 and the airbag sensor - an accelerometer - is under the dash, below the console, in front of the shifter.

awesome, so I'm good to go. Thanks for the advice guys, and I hope I won't be slamming into anything like a wall anytime soon Scoob ;)

If you're making your own bumper, remember you don't have to overbuild it since they aren't being used as a battering ram. 3/16" is as thick/heavy as you should ever go with a bumper.

I disagree. IMO you can go to 1/4" depending on the application. I'll be making my rear crossmember/bumper out of 1/4" because it will be supporting the rear tub and must take a good hit and be safe for recovery points. Rather go overkill and never have to worry about it.

Look at the best/most solid bumper "hardcore" commercially produced designs and you'll find that 3/16" is plenty. Really. The more weight you add unnecessarily, like 1/4" armor or bumpers, the worse your Jeep performs both on and offroad. :)

Or if you want to be sure, just disconnect the battery and give it ten minutes to let the circuit loose voltage.
