Can I replace with another shackle or am I screwed? If I figured this out right, if I replace the shackle and compress the leaves tight this should raise the bed up.
Thanks,
Chris

Is the shackle mount worn out or the shackle itself? The shackle can be replaced with one from a supply house or if you need a new mount I have one I took off mine you can have. | | | | | Joined: Jan 2004 Posts: 288 Shop Shark | | Shop Shark Joined: Jan 2004 Posts: 288 | It appears to be the shackle, a metal band that wraps around the leaves. I think the problem I may run into might be where the leaves mount, there are no bolts through the bushings, it is welded in place. I mean a rod inserted then welded, instead of bolting it on. You gotta love P.O.'s.

It may raise your bed up until you drive it one time and they will be spread apart again. Their purpose is to keep the springs aligned and should not even be tight. They do not hold the leaves together. You need to have your leaves re-arched or replaced. This is common for all of these old trucks, if they were used much at all they are now sagging.

The rear springs on my 55.1 were worn so bad they were arched up in the opposite direction. When I installed new springs my truck was raised a full 7 inches! The shackles are what hold the rear of the springs to the frame bracket.

Thanks,

Don't know what you'll pay for re-arching but it is a hell of a lot of work that justifies new springs while you are there. You can replace them for a hair over $100 each if you can avoid shipping costs.
Make sure you block the truck up very securely in front of the springs before getting underneath!
