Is my jeep ok for wheeling in rocks?

Right now I have a 2" spacer lift on my 98 TJ. I'm about to add XJ springs to the front to raise it an inch to compensate for the winch. When I installed the lift it came with 2" bumpstops which I did not install. It seemed I would have no flex this way. If someone can post what they have done it would be appreciated. Also are my stock brake lines ok on this setup at full flex?

Wheel it, break it, fix it and repeat. As far as your brake lines flex it out and see if you still have some slack.

I have a 2" spacer lift and no winch....I cut away most of my front bump-stops (they were extended by previous owner for running a plow. They were almost always contacting, making for a rough ride and no flex. Now they barely ever touch the axle, if they ever do at all)

I'm able to disconnect my swaybar and go full flex without damaging anything. I rub the right fender sometimes if I turn the wheel full right while flexed but I haven't damaged anything and I don't think I'm hitting the bump-stops.

Tire size? It's hard to answer the bumpstop question without knowing.

Rocks probably won't take kindly to the nerf bars but they'll get beat on before your rocker.

The only way to tell if you're going to have issues is to cycle the axles completely and see what's what. There is no shortcut to this. With a 2" BB and no additional bumpstop you should be getting coil bind pretty good (it's actually not good but...) and probably having other issues on the droop too.

^^^This. You need to make sure you are properly bump stopped to ensure maximum flex without breaking things. Unless you just like to buy shocks, tires, suspension parts and fenders.

How can I cycle it using one of the hydraulic lifts? I'm going to be working on it in my uncles garage and he has one installed. And when I do cycle it, should I disconnect the sway bar links like I will when I'm on the trail (the front ones at least)

why would you not install a necessary component in your lift? i don't get that. are you trying to destroy your springs, shocks, fenders and other important things?

see the suggested tech readings link below? click that and get reading.

lastly, if you bought a 2" BB to gain flex, you bought the wrong stuff.

I lied. There is a shortcut. Extend the bumpstop the same as the lift pucks.

I have cycling to gain maximum useable travel on my mind because that's what I need to do to mine.

I would suggest a few skid plates underneath if you don't already have them. Gas tank, steering box, and oil/trans pan.

I am on 31's right now and plan on staying on them. I did not add the spacer lift for flex, I realize that. But I am adding the xj coils to raise it an inch to get rid of the rake. If it rides bad I'll swap them out again no problem. I just don't want to lose my brakes while on the trail or any other important components. So since I have a spacer lift, are you saying extended bumpstops are not necessary?

And I have rocker guards, my profile picture is an old one from last summer

based on what's been said so far in this thread, what gives you that idea?

would you like to prevent damage to expensive parts? do you want to get coil bind and long term problems with saggy springs? do you want to rip the shocks mounts off your axle? do you want to break bar pins? how about fenders? do you want to damage those significantly? you don't want your spring to fall out on the road do you?
Help fast! Rear Spring Fell Out (yes, right now at night)

Here's how you set bumpstops up. Make sure you're using extensions, not hard poly jounce bumpers. Here's why.

Thank you guys! I'll check it out this weekend. Getting ready for a trip the summer. Went last year stock and was fine but looking to do some harder trails this time around.
