    in order for it to go side to side each bar woulld need to move sideways with that piece welded to both bars it cant move as easily um lets see if i can explain okay try this look at the pic of the ssc 2 link now try to picture in your head it bolted on with axle try to moves the tires over you'll see the bars when welded together would want to move forward also not just sideways say you pushed the wheels to the right the right arm would have to move forward since they are solidly welded together which it cant do because its securly bolted to the frame
    i thik that 2 link would work very good

    The bushings where the two link attaches to the frame are the portion of the assembly that allow the axle to shift side to side. When you bolt your axle to the 2 Link bars using the u-bolts it is a solid, rigid connection that does not flex/twist/swivel at all. The axle itself effectively does exactly the same thing as that crossbar. The cross bar is merely redundant.

    Either way, the entire setup will shift side to side due to the bushings. The bushings allow the shifting, and the shifting will cause the bushings to wear out. As the bushings wear out the shifting will get worse.

    What do you think holds leaf springs in? its rubber bushing!
    KAPOW!

    the axle isnt welded to it its held on by u-bolts which can loosen up and allow more flex this is a permanant weld
    it just looks to me like it would work a whole lot better than a reg. 2 link

    A rubber bushing in front of the axle and another one behind the axle, which when used in conjunction with each other limit the lateral movement of the axle. They are designed with this in mind. If you remember yesterday I explained that leaf springs are an engineering compromise. They kill two birds with one stone by provide the spring force for the vehicle as well as locating the axle, which in turns lowers the cost of the suspension for the manufacturer. The reduced cost is the only reason why a manufacturer would want to put leaf springs in a vehicle today, due to their poor performance and handling characteristics as compared to multilink and SLA suspension designs.

    If your u-bolts loosened up you need to go back and retighten them. Period. That should always be a solid connection.

    If you're 2 Link bars are 25" long, and the bushings allow them to shift only 1 degree (which isn't a lot right?), that would translate out to the axle shifting 0.44"....

    That's only 1 degree...

    2 degrees it would be 0.87"
    3 degrees it would be 1.31"
    4 degrees it would be 1.75"
    5 degrees it would be 2.18"

    5 degrees is not a whole lot of movement at the bushing, but at 25" out at the axle it translates into some serious movement. This is why you need a panhard bar.

    LISTEN TO ME!!!. I tried it without a panhar bar and it didn't work. IF you don't believe me. Try it yourself and learn the hard way. It is that simple. Don't know how else to explain it. We are here trying to help, not to be Ass holes. If you feel we are being "pricks" so be it.

    Leaf springs are on trucks so they are able to haul things. Not so they handle like sports cars.

    With the ssc kit the plate thats connecting the 2 bars turns the suspension into a swing setup. There will be no side shifting because of the plate. Think about it. You guys are making this more difficult than it has to be.

    How about you guys put an end to all this crap. NOW

    How about you realize that you are thinking about that wrong?

    The suspension is already a swing setup. The flex comes from the bushings. Unless they are running steel bushings that don't flex, the axle will shift. Period. LOW PSI has even tried it this way and is agreeing with me...

    Trucks would be just as capable with coil springs and SLA suspensions. They are just more expensive. However people are pickier today and want a better ride, even from trucks. This is why fullsize 4x4 trucks today are SLA suspensions with Torsion Bars in the front, instead of the old school leaf spring front suspensions. Heck even Jeep runs a coil suspension on the current Wranglers instead of the historic Jeep leaf spring suspensions.

    they will flex but the way the bars are welded together it cant flex that far those bars have to remain parallel because of the way they are welded and they wont be enough flex for it to cause problems

    Argh...the bars must remain parallel even without that crossbar. But the bushings will still flex enough for the axle to travel more than wanted. 5 degrees of flex in a bushing is not a whole lot. Pull out a protractor and take a look at how big 5 degrees is...

    Not very big...any rubber or urethane bushing is easily capable of allowing such deflection.

    What works is a panhard bar.
