jk bumpers
I agree there are scenarios such as you describe in which it may be advantageous to have a shorty. I was just pointing out that there are other scenarios where the full-width protects you. My experience is that the later scenario is more important for me. Maybe I just don't pick good lines!

And, if that's what's more important to you, wonderful, I don't know if I ever tried to claim that a shorty offered any protection at all. Afterall, that isn't the point of a shorty bumper.
Maybe a pic will help your confidence?
Yes, I thnk you're right here - and we may be saying the same thing. The feds don't want your airbags to deploy on a low-speed, non-threatening impacts- hence the crush cans. And you're right, they're only really valuable when they're taking the energy load. An impact on another location of the bumper, say on an outside edge, for example, is going to be absorbed by the deformation of the bumper. But, a hit right on the end of a frame rail will transmit a lot of energy because the frame won't want to give. Without the crush cans, you could get a happy face of airbag!
Here's a couple of pics (used by permission) of the "overlay" of the AEV bumper compared to stock. A lot of us like the AEV because it is attractive.... but in this case beauty is more than skin deep. There's a lot of engineering behind this design.
Okay, in all seriousness, I think it's safe to say that we all know you absolutely LOVE the AEV bumper, maybe know a guy or two who works there and will defend it's merits to no end while talking down the design of lesser bumper manufacturers. I'm sure if pulmano1 has any other questions regarding AEV, you're the guy to talk to
I too think the AEV bumper looks great and like the full width protection, however, I question the strength compaired to some of the others. I have seen pictures of the open back side of the AEV and side support bar. I can't wait to see on in person and how they do on the trails. That goes for the Fab-fours bumper too.
When people are talking about full width protection, what are they referring to?
Seems to me like anything that sticks out past the body tub would be more of a liability than anything else. I would rather replace a cheap fender flare than a $1200. bumper. I just don't see the advantage of something like the AEV other than the bling factor. I can see taking that greasy turn and sliding a little more that I would have liked, catching the end of my full width $1200. bumper on that tree adding a new bend that doesn't really flow with the others. That same slow bump on the tire and I just mutter something under my breath, back up, get back on line and keep going. Maybe have to get an alignment when I get home. At least I'm not shelling out another $1200. to replace a deformed bumper.

Anyone here know what material the AEV bumper is made of? This factoid seems conspicuously absent from all the descriptions I've seen.

Speaking From Personal Experience, In May of 2006 I hit a deer, I was going 55 mph, and I had a Home made Full width Bumper and when everything was said an done there was no damage to the Jeep. The Insurance did infact total the bumber though, they replaced my home made Bumper with the Body Armor Full width Bumper with all the hoops. Then on December 26, 2006 a Cadilac Escalade made a left hand turn in front of me I hit the Cadilac, $13000.00 damage to the Cadilac, $4000.00 damage to the Jeep.
I know I made my case for the AEV bumper, I have never had a problem with approach angle either. I like the protection of a full width Bumper.

How does a "full width" offer any more body protection than say a 3/4 width bumper? Seems to me that once you have the body covered in front you would be good. Kinda like the old saying about anything more than a mouthful being a waste :toung:
I will say that I do love the look of the AEV.

As far as approach angles go, I have no doubt that your 2x4 constructed Body Armor or even home made full width bumper that you had on your TJ would have provided you with very good approach angles as a 2x4 is slim. However, you cannot deny that not having a bumper where your tires are would give you virtually a 90° approach. Also, we're not talking about the TJ here but rather a JK and a JK with a HUGE front bumper that literally goes from edge to edge is much taller unlike a 2x4. Even looking at the CAD drawings you can see that it's approach angle would be just a little better than stock and a stock Rubicon with 32" tires is just under 45°. Heck, even with my WARN front bumper (which in reality isn't a complete full width bumper), I have already had it get in the way of rocks I've been trying to climb on moderate trails. Granted, bigger tires would help improve this a lot, but I think you're kidding yourself if think it won't be an issue. Or, at least I should say, it has been an issue for me so far.

Kidding myself, hmmmmm (I Love A Good DeBate
) I guess, wayoflife, that I have only owned Long Wheel Based Jeeps and I expect contact with Rocks, Ledges, and such, especially the rear Bumper. The LJ has a 10 inch rear overhang which the TJ does not. The New JK has the Same and is longer so I expect I will have some issueas well, I choose to have the LONG WHEEL BASE so I then Choose to have these problems. I guess I have Never really notice any other way. Papabear
There will always be scenarios where the cans will be missed, and their purpose will be lost. Here's the bottom line: In a direct frontal impact, the cans have been engineered to crush - absorbing the energy that may otherwise deploy the airbags. So, if you're in a AEV-equipped vehicle and you rear-end or t-bone another vehicle at a modest speed, the design of the AEV **MAY** help to mitigate the chance of an unnecessary airbag deployment. The net, net of my point is that all I am saying is that AEV is paying a lot of attention to the preservation of the safety attributes of the OEM bumper design. And I am NOT saying that AEV is alone in factoring this in. Others may be too. It is simply a buyers decision to weight this design in their respective buying decision. It is NOT the end-all of all bumper differentiation. (I chose it because I think it looks good!)
I don't know why you are compelled to attack me. The models were provided to tell i.e. "show" the close design comparison between the AEV and original bumper. We both know that most companies are using CAD but I thought some of the forum members would like to see an aftermarket to OEM comparison - so that's why I posted.
". But, when you say things like "A lot of us like the AEV because it is attractive.... but in this case beauty is more than skin deep. There's a lot of engineering behind this design" in the context of promoting AEV, it sounds a lot like you're suggesting that other manufacturers don't put a lot of engineering behind their designs. Or, at least, that's how it sounded to me.
I take offense with this comment. I have never talked down the design of "lesser" bumper manufactures. I'm not even sure who I would consider "lesser". There are plenty of VERY good front bumper designs out there for the JK. I like a lot of them and I could see purchasing any one of them. I prefer the AEV over some of the others - but most of my decision is purely a subjective one based on appearance. Others here prefer the function/appearance of other bumper designs and I applaud their decision!! I really like that not all of our Jeeps will look alike!!
