Those might work, but, I suspect that some of the upper leaves won't allow for installation..... too thick.

 

Yeah, that's true. Didn't think of that.

To install these spacers, will I need to take the whole package apart? I have never done that though, is that an easy task once the spring is off the car?

 

They are usually strapped together..... and sometimes, them fellers ain't easy to remove...... Might be easier to wedge the spring open a bit, insert the insulator, then pull the wedge. Could probably do it like that with 'em still on the truck. Just jack it up by the frame, to take the load off of 'em.

 

Sounds doable.
Wanted to remove the lift blocks anyway now that I got new U-bolts. So have to jack it up anyway.
Ordered some of the Dorman parts and will see how it turns out.
Thanks so much for your help!!

 

Let us know how it goes, and if they actually work.
