SRT rear swaybar effect on quadralift?

I know the SRT rear swaybar will flatten out the cornering on my quadralift equipped jeep gc which has me really wanting one since i do twisty mountain roads all the time. Other people have said that it will have a negative effect on offroading. With a standard suspension and solid rear axle that makes sense to me since you likely would loose some articulation in the rear suspension when offroading.

BUT since the quadralift is a different setup and the QL is so stiff when in offroad1 or offroad2 mode and has very little articulation, would there really be any negative effects to the quadralift rear suspension with an SRT rear swaybar installation?

it seems if the quadralift can still reach offroad1 and offroad2 heights with the SRT rear swaybar then there wouldnt be any negative effect offroad. Is that correct?

Thanks

Re: SRT rear swaybar effect on quadralift?

Increasing your roll bar stiffness increases your effective spring rate. A higher spring rate means less articulation regardless of what suspension layout you have as nothing can negate the physics. The real question is does it matter? My guess would be that it will do little to degrade the cars off road ability, the suspension is quite stiff as it is and the roll bar is not much of an increase in torsion over the stock piece. If you want to get all steely-eyed you can always disconnect it like the serious folks do.

Re: SRT rear swaybar effect on quadralift?

Thanks for the response.

would i be correct in assuming that increase in effective spring rate is only under cornering loads? Or would that show up in any situation, even at slow speed say going over speed bumps in a parking lot?. The sway bar kind of leverages one side of the suspension against the other under cornering loads right, so in non high lateral g situations it wouldnt have much effect?

would the sway bar effect rear tire "drop" where the rear tires wouldnt have as much reach? Is that what you mean by it effecting articulation regardless of suspension type

not looking to disco the sway bars, just trying to figure out if my rear wheels will be off the ground on moderately rutted roads on my mountain if i change the swsy bar to get better handling on the twisty roads here.

Thanks

Re: SRT rear swaybar effect on quadralift?

No anytime the suspension is at different heights it loads up the bar, whether this is caused by cornering loads or any other external factor makes no difference. Anytime the wheels move relative to each other the bar is loaded (put into torsion) and this will have the effect of transferring energy from one side to the other. This is why your effective spring rate changes, as a force (hit a pothole for instance) tries to push the tire up on the high side that force must now overcome this extra energy as well in order to articulate the suspension.

Realistically the sway bar is cheap enough that you could simply try it and see what happens and lose little if it turns out you want to go back. The proof is in the pudding.
