I want maximum travel so if I need to use bump stops, I would rather go with a 4" lift if i need to to gain articulation.
Your travel will be limited to how long of shock and how much bumpstop you lift has. My coworker is running a 3" TeraFlex LCG on his with 37's but add the 4" bumpstops to protect his fender wells. He only trimmed the pinch seem and is running stock fender flares.

Well put. We could not agree more. Save the cash and put in the X Factor Long Arm System.

You will not have to trim the pinch seem with our system either!

running a 4" bumpstop seems to be countering the whole idea of having a long travel suspension. I have flat fenders and don't mind doing the pinch seam mod so I guess I'll see what I'll need for bumpstops based on what tires I go with.

I am a noob in the 1:1 world. any professionals want to weigh in on why someone would get a LCG long travel suspension only to limit it with bumpstops? Am I missing something?

im no expert by any means, but something about , bump stops prevent over extension of the shocks, which will damage them?

You are not really limiting it at all. The point of a long arm isnt for compression, its for droop. With a short arm, as the axle droops, the angle of the arms can change drastically if they are short. In back, this can lead to a rear steer effect, where the side of the axle that is drooping, starts to move forward. This causes the axle to be at an angle causing the steering effect. The same can happen up front, but typically to a lesser extent as the front arms are longer than the rear.

So a long arm, because they are longer, have a smaller change in angle. This prevents the axle from moving fron to back as the suspension cycles.

You also end up with much better axle control, so the street handling can be increased quite a bit as well.

So, adding bump stops (which WILL be required with anything over a 32" tire) will not take aware from the long arms.

bump stops are for the other direction, they are there to keep your axle from smashing into the frame, but mostly they are there to prevent overcompression of the springs

so what limits the travel the other way to protect from over extending the shocks? wouldn't it be the bumpstop on the other side? I've built scale rockcrawlers with 4 link suspensions but never had a reason to use bumpstops on the little guys. I ran a half sprung half droop suspension with the springs inside the shocks, half the spring above the piston and half below. If only the jeep was that easy.

i think the shocks themselves limit the travel so its not really possible to overextend them, unless of course something prys your axle off of the vehicle

your shocks CAN limit your travel if they are not properly matched to your setup, but they're not supposed to. over extending/compressing your shocks can damage them. bumpstops should control compression, or the upwards travel while droop is limited by the maximum amount of flex allowed by the suspension or limiting straps. i'm not an expert, and feel free to correct me, but i do know that shocks are there to dampen the cycling of the suspension, not to control the limitations of it
