A question about Articulation

Here is another newbie question. Can you tell me the difference between suspension travel and articulation? Coming from a desert background, we always talked about how much travel we had. With jeeps, it seems articulation is important. But what is the difference?
Also, if I were to get let’s say a Rubicon Express 5.5 long arm lift for a TJ, will this give me more suspension travel or articulation than the stock suspension? I was thinking of adding 37” tires to a TJ with as little suspension/body lift as possible by adding flat fenders and whatever else I can do. My thinking is to maintain as low of center of gravity as possible. In doing so, will I be giving up on the amount of articulation I could gain by going with a big suspension lift? Thanks for your help!

Articulation is just another word for 'flex'. It has no real bearing on travel. Defining travel is more specific and useful. Travel is measured at the shocks.....if you've got 12" travel shocks, you've got 12" of travel. Then you can separate that into up and down travel. A suspension will travel as much as the shocks allow, given there aren't any constraints in the way. It's up to you to use parts that can handle the travel and also make it useful, not wasted. I would not recommend RE but that's simply my opinion. Much better stuff out there if you're looking for performance.

With 37s you need bigger axles too

Yep new HD axles and gearing.
Most people like their jeeps to be as high as they can make them. But I would like to keep my center of gravity as low as I can. I will be rock crawing and I want the groud clearance of the 37" tires. I was hoping to only do a 3.5" suspension lift and run flat fenders and maybe some sheet metal cutting. Can this be done?
I was concerned that with a 3.5" suspension lift I will be losing travel and or articulation compaired to a 5.5" suspension lift. Is this correct? Does a 5.5" suspension lift have more travel or suspension lift than a 3.5 kit???
thoughts???

this rig ran 37s on about 2" of lift.



I've seen it in person and the amount of fabrication required to make this true LCG rig work was astounding. Notice there are no fenders and a fiberglass hood. The rear section of the tub was completely cut out and high clearance fenderwells were installed. There was lots of hard work put into bumpstop and shock lengths.

Not those of us that actually wheel where stability matters.

Not a new concept man. 3.5" over stock is pretty standard for 37's. I would consider 5.5" too tall.

Good to know. As least I know I'm on the right track. I'm still on the fence if I should build a yj or a tj. I keep going back and forth. I think I'm back to a YJ (for now). I can get one for much cheaper. I'm going to replace the suspension with a new suspension lift. I putting new front and rear axles on it along with new rims and tires. Not to mention new fenders and bumbers. All I have to do is make sure the engine, trans, and TC are good. I keep reading both pros and cons to leaf over coils. This will be my second car so one road ride is not a priority.
