Running Without a Rear Sway Bar

srimes said:
I'll stick my neck out here and agree with Jerry about leaf springs. Twisting them (ie, when articulating) makes them stiffer so they resist flexing much more than coils do, and they are less likely to require a sway bar. People with leaf sprung crawlers have gone to great lengths trying to reduce leaf twist and allow more articulation.

Are you going to explain how the antisway bar locates the axle and defines its travel path despite the coil springs being unstable in all directions? No one has done that yet.

And while you are at it, why did Jeep put a track bar and an antisway bar in the YJ if leaf springs are so stable? Even the CJ7 had an antisway bar.

I still don't see how front disconects are a hindrance and only used by newbies in slow speed crawling scenarios. I always thought you wanted as much articulation as possible when going over uneven or off camber obstacles and trails.

That's where this always gets all fucked up. You take a simple premise, "articulation is good and the front stock swaybar limits articulation" and then use that to create a bunch of rules that are perversions of something basic and simple.

Yes, the front swaybar does limit articulation so running disconnects is an improvement. It is not as much of an improvement as running an offroad type swaybar like the Anti-rock. The "front is bad" then gets used to make the rear one bad as well under the false premise that if the front is bad, the back is bad as well or worse, put disconnects on it as well.

Taking shocks out of the equation, running an offroad type swaybar at both ends will always result in a more capable rig where traction and stability matter. That is about as simple as it gets.

Then you could have something that makes everyone right and wrong , Quarter elliptical leaf spring.
These are way cool if done correctly.

That pic shows exactly why sway bars are important. While it looks cool with how far up the ramp it can go there is no balance between the front and rear suspension.

A little video on removing the sway bar... I know it's a JK, maybe someone can do the same test on a TJ?

I'd like to see the test on the same jeep but with proper bump stops.

Spring rates have a huge impact on roll stiffness. The rear springs have a lower rate so they articulate more easily. The rear sway bar stiffens this up and balances front/rear articulation.
 
I ran without a rear sway bar while waiting to install my anti rock.

I can't say it was fun. The jeep felt like a boat.

So is articulation improved with a ANTI sway bar? and is articulation not important?

We need to start posting this image as response to these ramp photos. Because flex on a ramp is all that matters, right?

Of course running your 2 wd passenger car in deep mud should be included , For fucks sake your actually dogging a CAR that in 2021 dollars would cost $4020.00 and likely could out ramp and out mud run a stock TJ ? .......:rolleyes:

The model T would put many of todays 4x4s to shame off road

Articulation is ultimately determined by the shocks.

True I fully agree ! , but how is articulation IMPROVED by ANTI sway bars? Basically is an unlocked Jeep with ANTI sway bars more capable then a unlocked Jeep without ANTI swap bars? And what if both are locked? Not trying to be a dick but at some point OFF road I fail to see a huge advantage. On road I definitely want an ANTI sway bar !!!!

Think about it as controlling movements. Without sway bars and without adequate shock damping, the body will flop side to side as the Jeep moves through the terrain. The weight shifts uncontrollably towards the downhill.

Add in antisway bars on both ends that also allow for full shock articulation and you create a system that tries to keep the frame parallel to the axles. When the axles articulate in opposing directions, the antisway bars work to keep the frame centered between the forces of the articulating axles. The movements created by weight shift are controlled. Controlled movement aids in stability.
