Howdy I have a 89 Bronco II SASed with a D30, I've built everthing. Long arms by me. Trailgear flex joints, Built to the same specs as everyone one does. I believe it is stiff, my coils are Rustys 6.5" coils, shocks are bilstein 5125s. I'm thinking its my coils and i need taller shock towers (to allow me to run longer shocks.) I've pulled coils/shocks out and i can push my axle into the frame. I've got no binding on my long arms. I just want another opion be for I start dumping more money in it. Do you guys think my coils are stiff? I love they way they ride, they are amazing going down the rocky/bumpy mountain roads, but being that this is a trail rig, it needs to flex to the best of its ability. I also need to set my bump stops and need to do limiting straps but i can't do that untill i know what my max flex limits are. Right now it just seems like i could go more, but somthing is holding me back....

 

honestly how new are they? Newer springs are going to be stiffer. My lift took nearly two full years to settle and begin to flex like it does now.

 

Are your trackbar ad drag link the exact same length?

 

I thought length wasn't an issue? it was just the angles between the two? or is that only relative to bump steer?

Oh... and on an unrelated note... what in the world is the stock setup on these called? with the split axle?

 

I thought the same thing? They pretty close to the same angle, I dont have hardly any bump steer but, i'm going to go to chevy one ton steering. Anyways my lengths are....Drivers to y-link 42"s, Passenger side knuckle to pitman arm 36"s and my track bar length is 34"s around.

And The stock suspension is called TTB (twin traction beam)

Also i would just call mine stiff when flexing, they are pretty much brand new have under 20 miles on them. They are great going up the mountain bumpy roads just they don't seem to flex very well (I was told). but I've also thought they may need some miles and break in time to. I'm just trying to get some more opions. I was told and read nothing but good about rustys coils. Trying to get things figered out.
