Is It Safe...?

Is it safe to drive at highway speeds with the rollbar piece removed that attaches the main roll cage to the windshield? (on a '99 TJ)
I don't know if the windshield is structurally sound without those bars or not....

I don't really know what piece you are talking about but I am going to go ahead and say that if you have a roll over incident and you have compromised the structural integrity of the cage you will end up as roadkill.

I have experience with this

Yes the windshield is safe. The windshield is what mainly supports the front of the jeep while the rear "dome" bars support the rear of the jeep. If you want legit proof go remove the 4 bolts that hold the spreader bars (the ones your talking about having removed). when the bolts are free grab the end of the bar closer to the windshield and pull down on it (not too hard)** and you'll see that it bends down quite easily, this is because the spreader bars are only held by 1 bolt through the main roll bar structure and the 2 bolts that tie into the windshield

**If you've never removed the spreader bars before then they'll probably be stuck to the windshield (of stuck under the visors, I'm not sure with TJ's but my YJ's were) so if the are just kinda jiggle it a little

I would venture to say that those bars should only be removed when lowering the windshield, I'm not sure what purpose they serve exactly. Why would Jeep put them there if it was safe to drive without them?

The same reason they put the rest of the "cage" in. Looks.
The factory cage is not a roll cage.

I concure, the only time my spreader bars are removed is when I plan out a week or so with nice weather to put my windshield down

I'm gonna say its because jeeps look weird (aside from the CJ's and 1987-1991 YJ's) imo when the windshield's up and the bars are removed

Really?

Then what is there to protect your but from any kind of roll over? It's a cage in the simplest form. It's not there just for looks, it's there as a safety precaution, as little as what it does protect, it's the difference between a bruised head and you being a skid mark.

Those "spreader" bars are to spread the crushing load and forces impacting the windshield, around you and to the rest of the simple cage, and keep the windshield from cutting you in half when bends backwards.

Thanks Niel & Vaultzz.

AZTJ: I'll drive slow on the corners so you won't worry too much
J/K
I just wanna drive it for a day or two without them, to see what it looks like, and to have a respite from smacking my head on it when I get in, lol! I actually planned on putting them back in Monday since this is my commuter, and my fellow Idahoans can get a little 'pushy' in rush hour traffic - especially when it gets hot outside.

I have to admit, I agree with AZTJ, to a point. It is there for more than looks, but it's not going to hold up a Jeep in a rollover, whether I pull the spreader bars (thanx Vaultzz) or not.

Is it safe? So long as you don't plan on rolling over.

Will it bother the windshield to roll down the highway with the spreader bars off? No, it'll be fine. The windshield is supported at the base quite well. Many aftermarket full cages don't connect to the windshield.

I pull my spreader bars off and leave them off all summer so I drop the windshield quickly if I want to, I also like the "feel" of having them off.
