You don't get more travel with long arms. The reason people get long arms is exactly because of what you're describing above, but it's really only at the higher lift heights that you see a benefit.

Long arms do not increase travel.

TheDirtman

Properly set up there is a benefit at any height with long arms, saying only tall lifts benefit is a myth.

Unsprung weight such as heavier axles and tires/wheels are what helps stability not the above mentioned items.

TheDirtman

Exactly, anything added above the roll center decreases stability even though it may lower overall height due to coil compression.

The above replies something I didn't say.

I said -- "....a wider stance also helps stability....",
and -- "....steel bumpers, winch, skid plates, heavy duty rock sliders, etc., help in lowering the CG."
Besides, this should be read in the context of what I replied to.

'Stability' is a pretty wide term, which consists of many variables. Those include both the sprung and unsprung weight, suspension properties and geometry, CG of both sprung and unsprung weights, roll center, tire grip, and more.
At high speed, aerodynamics become an important factor in stability.

TheDirtman

Adding armor, winch, sliders does not help lower center of gravity and is wrong even the second time you stated it. Not sure what context you are talking about but adding weight above the roll center raises the center of gravity and makes handling or stability worse.

Quote - "adding weight above the roll center raises the center of gravity"

The body has a CG of its own, which can be changed by added load location.

Added weight on a roof rack raises the body CG.
Added weight at the bottom of the body lowers the body CG.

Both, regardless of the roll center location.

Can you elaborate? moreso on the noticeable part, i get the concept, but at 0" lift I don't see how you would notice. just curious.

TheDirtman

B would be the most stable and you make my point. The roll center on a jk is below the body so if you add a bunch of stuff to the body you will decrease stability and raise the center of gravity on the jeep.
For stability you have to place the weight on the lower side of the roll center or the place below the suspension pivots on the vehicle. If you place the same amount of weight on top of the jeep it would roll more then if you placed it on the bottom of the body but both would add instability to the ride.
