i just bought a 4 cylinder that ha a 3 link rearend and was wondering what each bar changes when adjusted? it has two bars on each side, then one bar running diagnally on the left side of rearend to center and a spring loaded pulln bar on top.i was told to buy steve smiths trackside chasis tuning guide and it talks about adjusting 3 point suspension,3 point upper link and third link lateral mounting position but not for sure what its try tell me.we took it out for the first time last weekend and it pushed all the way around the turn.any help would be greatly appreciated,thanks

On the lower link bars, when you put uphill angle in them it creates more bite in that tire. On the third link(pullbar) you need to take the track width times the left percentage. Say your track width (center of lr tire to center of rr tire) is 60", and your left side percentage is 53%. 60" X .53 = 31.8". Try to keep the pullbar straight in the chassis. The diaganol bar is the panhard bar, this help with side bite and body roll. the lower it is to the ground the more body roll, and the more angle it has the more sidebite your car will have. Hope that helps.

Did you mean it has 2 bars 1 on each side.
If it is a 3 link then this will help. the more angle in a trailing arm the more bite. Example RR flat and LR 2 inches up hill then the LR will dig harder than the RR. May push. BUT if you want Good help we need more info give us all the springs, weight %, bar angles, spring locations, are they on sliders, is it a J-bar or straight panhard bar? How long is the panhard bar? How long are the trailing arms? what frame mounts do you have? Does it have weight jacks in front...Etc.If it's adjustable tell us about it. You can also check out this site if you scroll down it talks about a 3-link and shows picture.
