So I was runnin a lame 2 link with panhard.. hated it so I built a 3 link with the bags on bars.. now I am gettin body roll around turned pretty bad.. I only have 4 valves as well.. im wondering if thats what my problem is.. maybe have to run 8 valves??? Any help is appreciated thanks

 

When you had the 2-link, your rear axle was basically a huge anti-roll bar. By going to a 3 link, you've lost your anti-roll bar.

 

Yes switching to 8 valves will fix it. 4 valves lets the air from the bag on the compressed corner escape to the other bag...

 

Cool thanks guys.. pretty much what I thought. Just wanted some opinions.. ill throw 4 more valves in there

 

So would any of the body roll in the rear have to do with me having 2800lb bags? Haha

 

Na. Why the hell you runnin 2800s? I'm rockin 2500 airlifts on all 4 corners...

 

Haha cause when I first bagged the truck. I did the 2 link and had 2500s on but they seem3d stiff. So I switched to 2800 but still didnt help smooth it out, so now I have these 2800s lol.. my buddy bought my 2500s for his model A build.. I got 2500 on front tho

 

on the bars changes leverage. on the axle, your spring compression to tire articulation ratio is 1:1. on the bar, the wheels have mechanical advantage at a ratio equaling wherever you put them on the bar. Basically, your effective springrate is much lower than when the bags were on the axle so you see more articulation. you don't notice the change in ride height because you're running slightly more pressure... pressure is preload, not springrate (till you hit max).

 

get off google.

 

yep this is correct.

but as mentioned adding the other valves will stop the air from transferring and it'll stop rolling so hard. mine is on bar at about 75% towards the axle. rides amazing.

 

Yea thats where I got my bags. Bout 75% toward the axle.. adding the other 4 valves made the difference for sure, its rides so good now

 

Or, as an alternative, you can weld an additional diff between the two bag mounts, which will give you back your anti-roll bar effect.
