Rear sway bar sizing Antirock

[AFeral]

Got a set of kings coilovers in the rear of my patrol Gq, getting a fair bit of body roll whilst cornering so fitting a rear sway bar. Thinking of getting an Currie Antirock sway bar

The bar is 50inchs long and .900 inch in diameter or 1270mm and 23mm in diameter. I want to run the swaybar outside the chassis rails, to try and get as much roll resistance as possible.
Any thoughts on why this size bar and setup may be a good idea or bad ?

Are you sure the longer bar gives more roll resistance.

Intresting point. I would have thought the further out the sway bars meet the axle the more roll resistance they would give. Thinking about it though, the longer the torrsion bar inbetween the arms that go to the axle the less roll resistance. As the torrsion bar would twist more, so using a thicker bar would give more roll resistance and hopefully still allow the rear to flex.
Does that sound right to you ?

The stiffness of the bar depends on how long the arms are and the thickness if the bar.

I have done some reserch on puting one on my patrol i was looking at 18" arms on a 1250mm long bar 27mm dia, and 39 splines on each end.

I have all the matiral there to build just got to busy to finsh...

I'm not sure, it sounds like trying to get more suspension travel with stiffer springs to me.

Shorter, thicker and shorter arms will give stiffer
Longer, thinner, longer arms and more angle on the arms at ride height will give softer.
