history of roll bar and full cage

Does anyone know on exactly what models the single roll bar was changed to the double roll bar?

Does anyone the history (date and models) of the full cage?

If we buy an older jeep (1980-1999) what can we do to it make safer?

We are looking to buy an old jeep to ride the grandkids around on our new farm and maybe take an occasional drive into town with the wind in our hair.

I am concerned about safety and want to purchase a "safer" jeep. I think a double roll bar replaced the single roll bar sometime in the mid 1990's. But I am not sure which model.

Any and all info appreciated.

It happened in the middle of the YJ run, 1992 I believe.
The extended roll cage was added to accomodate shoulder belts for rear seat passengers.

92 was the first year for the family cage. If you buy a Wrangler with the sport cage, a family style can be swapped in. it will bolt right in

Thanks, do the wrangler made after 2000 have any additional safety features? I am a paranoid granny and would pay more for the additional safety features '

With the gov't always adding new safety features you would think they would get safer each year!

Thanks again.

Do any newer models come with a full cage. I saw where someone referred to a roll cage as a family cage. That might be what we are looking for.

Early jeeps like CJ models had a roll bar that was behind the driver and passenger seats and then slanted back by the rear seat. The early YJ models had the same roll bar but added bars to connect the windshield frame. So early YJs had a bar going from the windshield frame, it ran along side where the door window would be and connect to the roll bar behind the driver/passenger seat and then slant back to beside the rear seat. Late model YJs added what is know as the family roll bar. All that changed with that is instead of a slant going from behind the driver/passenger seats down beside the rear seat, it now comes straight out and then curves down behind the rear seat. This allowed for the rear passengers to have shoulder belts instead of just lap belts. I hope that I explained where it makes sense.

Well mine is an 02. I don't know if you call it a "full" cage because it doesn't have a top bar back at the tailgate. More or less a full bar wrapping over your head, then side bars wrapping down to the tailgate, making 3 walls of a box more or less.

Also don't know when they started the passenger airbag on/off switch, but this one is an X model and it has that. You may want to keep an eye out for that feature as well. You can disable the passenger bag if you have a younger rider so it can't pop the cover off and slam it into their face. Generally I would have the kids sit in the back anyway but you never know when that might come in handy.

Thanks, I just did a google search and found
"1995 YJ Wranglers had no airbags. They put both passenger and driver airbags on 1997 and later TJ Wranglers"

I don't know if that is accurate or not, but it is a starting point.

Correct, 96 was a big guberment standard year (though virtually no true 96 wranglers exist). 97 and later will have more safety features standard than earlier models. My 94 has no abs, no airbags, very little computer control, an entirely different (and much less beneficial on road at high speed) suspension system, and virtually no common modern safety features.

In 92, the roll cage improvement allowed rear shoulder belts.
In 93, abs became an option. Standard on TJs, I think.
In 94, the high 3rd brake light became a feature.

In 99 or 00 the seat belt anchors for kids seats became standard.

You're gonna want at least a TJ, prob 00 or newer.

Unless ABS works with drums i think it was still optional on TJ's. My 02 has drums on the back. I haven't had to hit the brakes hard enough to see if she has ABS yet.

Also I never thought of ABS as a necessity. Had my last vehicle about 10 years. Never once had to hit the brakes hard enough to kick in the ABS. Sure there are retard drivers out there that will eventually force you into a situation where you need them. But if you're not out there drafting people nascar style (tailgating) and leaving a reasonable distance to the car in front of you, you will never put yourself in that position.

It'll work with drums, just not as effeciently. It is not a necessity, and is not a good thing for offroad (loose dirt or gravel), but is great for wet hardtop or turning while braking (b/c vehicles go, stop, or turn but only one at a time). 'Cadence braking' does the same thing but requires a more attentive driver (and as I said, I don't have it on my DD YJ, and don't want it). It seems most Jeeps that came with it have since had ot removed anyway, lol.

Appologies, I thought they became mandated with the OBDII requirements.

this is the old CJ style cage:


notice there are no windshield bars.

this is the driver/passenger style 1st gen YJ cage:


notice the addition of windshield bars

this is the "family" cage (92-06)


notice the addition of shoulder seatbelts for the rear passengers.

Now, when you say "full cage" around here, people are thinking of competition buggy style roll cages. These are normally used with 4/5-pt harnesses and racing seats. Kinda like a NASCAR.

Full cage:



Now, if a few thousand in fabrication & welding isn't your style, you can also add a "sport cage" to the existing stock family cage for added protection.

When talking about cages, you gotta understand there is always a compromise someplace. Either safety, loss of cargo space, ease of installation, or something. You have to pick where you want to make the compromise...and I'll tell you right now if you don't compromise some safety someplace, you'll end up with a NASCAR style cage you have to climb into, while wearing a firesuit, wearing a helmet & HANS device, and you won't be able to turn your head to see the mirrors.

This is my Jeep LJ's cage....a blend of Poison Spyder Customs parts, and custom additions. It's street friendly, and has no major loss in storage/cargo area, and was fairly easy to install with some skilled welding.



Look through these threads for more on full cage vs sport cage vs stock cage.

Thanks Unlimited,
It looks like we do want the family cage. You referenced (1992-2006).

Do all wrangler models between 1992 through 2006 come from the factory with the family cage?

Did they make the wrangler even safer after 2007?

Thanks again to everyone,

Thanks again to everyone,
from 92 and newer, all the wranglers came with a family style cage. there are slight differences between the ones found in a yj vs what comes in a tj and a jk.

the big safety changes between each generation do not really come from the cage it has, but the other safety features offered.
things like airbags. in that sense, a 2007 and newer wranglers will be safer than one from 1992. with the newer JKs you also have the option of side impact airbags that are supposed to bring the safety factor up over one with out them. however i am not sure what year those because an option.

Thanks schnutzy,
Coincidentally I just read where side air bags in the door was now an option. I don't see how that is possible. Unless the doors are not removable

i believe the side impact airbags are mounted in the seats, not the door. and the doors are still removable.
