front axle flex question

I'm getting my bone stock 98,5.2 ready for the blessing of the Jeeps jamboree. One of the tasks at hand is making quick disco front links. My question is will the added flex from not having the links in cause my front brake lines to extend to far? Or is there enough lenght in them to accommodate the extra travel. Yes I'm aware that I can fully flex it out in the garage to make sure. I'm just looking at saving some time by hearing if anyone else has done this. If it's a no go I won't waste the time and focus on other things. Thanks.

You should be fine, I flexed my stock ZJ out plenty of times without the sway bars.

Thank you. That's all I needed to hear. Now when we get everything going I will take the time to flex in the garage, both sides full steering lock left and right. Just to make sure.

I'd hammer the pinch weld back in the front fender wells too, just incase. Hate to see a popped tire.

I was running stock brake lines with a 6" lift for a few months. Successfully made it through 2 wheeling trips. It's sketchy, but it worked.

You must not have had any flex for some reason then. I would definitely NOT recommend anyone to use stock brakelines even on a 3"-4" short arm lift.

My stock front brakelines were almost stretched tight at only 1.75" BB and flex-joint LCAs and UCAs at full flex and steering close to lock. It worked though, but there really wasn't much slack left. I really don't see how the stock brakelines would be ok at 6" of lift.

I agree. I wouldn't recommend it either. Who knows... maybe the PO put on longer rubber lines.

Axle fully hanging. Brake lines were tight.

You can get a bit more slack in the brake lines if the bracket is left unbolted.

Note that disconnecting the sway bar does not create additional suspension travel. Connected or not your maximum extension is limited by your shocks.

If you get new lines use 1/2 ton GM lines. They are longer and dirt cheap My build has pics of the comparison

Well then my fronts have shorter shocks then the rear. Because I get great stock flex from the rear with that tiny sway bar. Compared to the front with that big ol sway bar. Seems kinda funny jeep would put different travel shocks on it. And yes all four are same brand and model. So why is it then that everyone else has discos. Didn't anyone give them this info when they went to buy them? Or are they one of those non functional parts that just look cool and jeep decided to put them on from the factory so they could charge more?

The sway bar itself is there to prevent body roll, I.e. suspension flex. That's why it's bigger in the front then the rear due to all the weight from the engine. True you can only flex up to the shocks maximum length but the sway bar connected will prevent that because that's it's job. So yes removing the end links will make it easier to obtain full flex/travel there for allowing the tires to stay on the ground a lot easier for traction purposes especially when you are not locked. But thanks for your knowledge.

It will still flex to the maximum extension with the sway bar connected. Just not as easily and, most importantly, there will be less normal force (i.e. traction) at the tire that is extending.
