Fabbing front sway bar for SAS...

So, how should I go about doing this? I want to keep it as simple as possible, just like to cut down a little bit on the body roll on the street, and something I can pop off when trail riding easily.

in 5 years of reading about leaf spring SAS projects i've never once heard of anyone making a swaybar for it. I really don't think there's that much body roll with leaf springs (in comparison to coils). Not trying to say you shouldn't do it if thats really important for you, I just don't think it will change a whole lot. Do you have a mechanical locker in the back? That will increase body roll when you go around corners compared to an open diff or selectable. Also did you put leaves in the back yet? Having the stock rear suspension with just taller springs increases anti-squat real bad since the links point so dramatically upwards, which also makes for bad body roll around corners. Having leaves out back or a long arm 4link helps.

No locker yet, and no leaves in the back yet. I'm thinkin of picking up a rear spool shortly though........

I guess just more of a reason to swap over to rear leafs when funds allow.

I was running my stock swaybar for a while after my SAS and I have seen others that do, and I cannot find my pics for some reason. I used my sway bar disconnects that I has on before the SAS and used a piece of 3x3 square that I mounted in the stock location and by using the 3x3 I could move the swaybar mounting location back a few inches and down 3" which was a perfect location. Yours may be different however. As far as making a difference on the road, I will tell you that your spring load is going to justify the body roll. If you want a flexy front end your leafs are probably soft hence a lot of body roll especially with the height. I ran the swaybar while I was using mine as a DD and it made a night and day difference. Now that I only use mine for the trails I took it off completely so I don't have to hassle with the disconnects.

I thought the whole reason for SAS was axle movement? Just kidding. I dumped mine on the IFS and haven't missed it.

if you DD the accord just forget the sway-bars IMO. It's a big flexy offroad truck, you should drive it as such. If you get too confident with less body roll I'd say thats a dangerous thing. Slow corners and lots of braking distance is the way to go. Go fast on the CBR

Here is a writeup:
http://home.4x4wire.com/erik/4runner/sas/#swaybar

I've not had a front sway bar on my '85 since I had crossover steering installed about 10 years ago. Sure, it leans in the turns but otherwise steers just fine.

When I load mine up for longer road trips, I end up with a lot of weight up high and get a lot of sway on the highway. Spooky amounts of random body roll to be honest. Like driving a 5,000 lb weeble wobble at 55 MPH.

I do have leaves in the back, SAS front, 35's.

I need to do something that can be disconnected for the trail. Is the front the best location for a sway bar... or could one in the rear do the job?

The front is the best because of the nature of the turning and pivoting of the tires. If you are parked at turn your wheels you can see how much it leans without even moving.

Thanks... that makes sense. I'll follow this thread and see what further ideas show up for a front sway.

I put on the rear bar for a while and found it made a very noticeable improvement in high speed handling on my '85. I took it off when I swapped springs (end links were too short to fit) but will be putting it back on when I get the rear suspension and axle set up the way I want.
