Well, thats a pretty good guess! Its loud enough that you have to yell over it, its got cracks in the vacuum lines so it sputters a good bit, and backfires every time you let off the gas :oops: I absolutely hate that YFA carb... I just started a build thread on it if you guys want to check it out. Anywho, lets get back to the flexing! :D

Interesting factoid. The more flex a vehicle has, the less stable it is.

Ever notice how super flexy buggies use sway bars. A Range Rover sport is incredibly stable and has fantastic handling. Doesn't flex at all, unless you push the sway bar disconnect button. I loved to watch these super flexy buggies on mild off camber situations Just lean like they were going to fall over. My CJ has a track bar on the front and drives very well down the road. I also have never wished it flexed more. I would never have a Jeep that drove like crap on the road so it could have lots of travel off road.

I would rather drive my tall wide wag on 38's w/o a sway bar than a tall narrow cj on 35's with a sway bar anyday. In an evasive maneuver or hard cornering I bet the cj rolls over first.

edit: agreed that more flex = less stable. Just not convinced that having a sway bar on a cj will make it any better than a wag or j-truck w/ some flex .

My CJ is also tall and wide. I am trying to figure out how to lower it and keep the 35's. I said track bar. I do also have a sway bar that I unhook offroad, only. My current Cherokee will have sway bars front and rear. I am trying to figure out how to get a track bar on the rear also. Not as easy on my Jeep as you would think.

Your taking one very specific situation to make a very general statement.

Here's my 79 Cherokee Chief with SOA and shackle flip. I would also like to add that I built this vehicle to be a trail capable and comfortable rig to enjoy the trails with my wife and my 5 and 8 year old girls and still be able to use it as a daily driver. I feel I have created just that. We just came back from our second year at the Halloween Spook Rally here in Arizona, which is a great, nighttime, off road game put on by the Arizona Rough Riders 4-wheel drive club, where you pick up clue sheets that give directions to the next checkpoint/ haunted house. That's right, they set up haunted houses in the desert! It's a timed and mileage tracked event. That is what I call family fun! The ride difference from the 4" spring lift I had last year was amazing. Our kidneys and backs certainly appreciated the change.

The way I see it is if I wanted a vehicle for blasting through the switchbacks, I'd buy a sports car and I'm certainly not going to spend close to $100,000 on a Range Rover and then tear it up on the trails. Who am I kidding, I CAN not and WOULD not spend that kind of money on ANY vehicle. The Jeep is awesome on the trails and handles just fine on the highway, as long as the sway bar is connected and I remember I am driving an off-road vehicle and not a Porsche. That is all.

Sorry if I drifted from the subject a bit.

One thing I've always been curious about is how much wheel travel it takes to flex like this. Has anybody measured theirs to see? I see the baja rigs running high-zoot suspension to get absurd travel. But y'all seem to be getting perfectly respectable levels of flex from basically stock pieces.

Aren't there aftermarket swaybar disconnects? I'm definitely going to run swaybars on mine. But it would be nice to be able to easily disconnect them for rougher trails.

Clearly, with a trac bar and no desire to have more flex on your jeep, you haven't left a powerline road. Ever.


I'd have to disagree with you. Your experience has obviously been with less than ideal suspension setups. There are actually a lot of things that go into making a balanced suspension in a rig, which most people aren't capable of or don't wish to spend the money to do it correctly. I would never opt for a Range Rover sport for any reasonably serious wheeling scenario.


Here is my Cherokee from back in the day... Very stable with this suspension setup.

Carnage BV twice and Patriot once. Two of the hardest trails in Colorado. Not to mention Upper Woodpecker and Highway to Hell in AZ. No problem with articulation. And I was on AT tires. I'll post pics as proof later.

Your suspension isn't that balanced, you have more articulation in the rear then the front. That is an issue when using coils springs on one end and leaves on the other, in addition to the narrow spring spacing of your coils. Leaf springs have progressive spring rates and that is what is making that Cherk stable, especially when it has more weight on the front. An un-chopped Waggy or Cherokee has more weight on the rear, though not by much. It is due to the wagon body style.

I've been wheeling for 15 years in four different vehicles. I have also studied suspension design and have coursework in vehicle dynamics. What you got?
