Thread: Four Bar Any Problem ??

Tweet

Thanks guys!! I am in the process of doing a new build, and was searcing thru a different Forum's build thread's when I came across this idea and this photo. I do not want to run a Panhard Rod as there simple is not very much room and a panhard bar even makes running the exhaust much worse. I am going to run a 4 Bar or Link or something and run two of the bars triangulated to avoid using a Panhard Bar or even a Watts Linkage.

Don, You know until you pointed that out I didn't see that problem. After studing that photo it is pretty plan that any suspension travel to speak of and something is going to either Brake, Bend or Mutilate itself to death.

Tech, God bless you man once again I complettly fail to understand what you are saying, maybe thats because its very late, or I'm just to dumb and have fried to many brain cells to comprehend. But thanks Dude maybe tomorrow after I get up and reread that it will become clear----I Hope!!

That's why I went back in the archives and found the thread I linked. If you will scroll down to post #30 like I said here, you will see in the drawing that I included there, that the Panhard bar can be any shape or twisted up like a pretzel to miss components. All you have to do is make the two attachment points the same distance from the tarmac, make the bar as physically long as you can (brake drum to brake drum) and make it from material that will stand up to the form you construct (make it stiff).

you do not need the upper bar if the springs are used.but if your using the bags? if yes to the bags then i would use a real four link and you would need a track bar .pan hard .or watts . less you triangulate the bars like Gm car or ford did it. then a track bar is not needed. if you use the stock springs and use a four link .or ladder bar then you should float the rear axle .all points for bars are base off the crank center line were i am from .more or less whats in the photo is a 1/2 ass ladder bar set up . the raise and fall of the rear axle is some what linear as if you hit a pot hole it will not move one side but the complete axle where there is some bind and good strong mount points are needed to deal with that..... but its not bad but not the best for ride were a 4 link may ride abit better but with a solid back axle its only going to get so good. i built them both ways with ladder and four links .my chevy is about the same set up as any car leaf spring car.i have floater i made many years ago moved the springs under the frame and used comp ladder bar s i had the car stock and the way it is now the ride is not that bad as some would think still better then many hot rods when you float the spring s you should use a track link bar of some kind to keep the rear axle from moving side to side as you do not clamp on to the spring over the center bolts with u bolts to hold the axle to the spring so you can get some side to side movement. SO why they have it set up like this in photo ? they do is for the bags as the upper bar having its owne mounting point will bind for the lower ride deal .i built mine for alot of power only...getting the spring eyes getting pulled out and spring whined up. pinion climb can be a very bad thing
