Re: What are these for??
Sorry if its a stupid question, but how does it help with heavy loads? Is it in case the bump stops dont hold up ,it prevents the frame from sitting on the axle?

Re: What are these for??
What piece are you asking about?
There is a helper spring at the left of the picture. But the thing next to the bump stop is the panhard bar. It keeps the rear end centered, so it doesn't move to the side, especially when cornering. The bump stop is the bullet shaped piece of rubber hanging down from the frame.

Re: What are these for??
Im talking about the lil drop down bracket that is riveted to the frame beside the bump stop.if you follow the frame between the panhard bar and the coil spring cup you will see it right beside the bump stop

Re: What are these for??
I'm interested in finding out also. I don't have these on mine, and haven't seen a reference to them before.

Re: What are these for??
Leon, apparently, yes. Interestingly enough, there's another recent thread asking about the same backets, and the pictures on that thread show them on both sides.
clips or brackets on frame ?

Unless it's a big block it didn't come with dual exhaust.

Re: What are these for??
I have never seen those, the 67 parts truck I had had coil springs mounted on the axle. They were small and they rode on the frame. I wish I had a picture.

They are the "positive stops" for the rear suspension travel. The rubber bump stop is a graduated rate. The positive stop is for when you've used all the rubber and need to prevent overtravel. It is an attempt to save the rubber attachment to live for another day and/or localize any frame damage to a part that can be replaced. You will find a positive stop next to the rubber bumper on the front lower control arm, too (different design but same concept). At least on the square bodies, anyway. K
