Poly leaf spring bushings
 

I ordered what I thought were the correct bushings for my leaf springs. Energy suspension 3.2126R. After installing them I found that they are too wide and won't allow the shackle to go back on.
Does anybody know the correct part number I need to order.
I have an 80 C10 SWB.
BTW, I was able to get the bushings in the leaf spring eyelets without removing the inner sleeve. Everywhere I've read says you have to remove it...that's why I figured I must have ordered the wrong ones.

How much too wide are they? Bushings are often a tight fit.

That part number appears to be correct, did you verify that they sent you what you ordered?

They have some odd stuff going on on their web site. They list 3 different size options for leaf spring bushings for 75+ C20, but none for my 73... so they certainly have some issues.

Looking at EnergySuspensionParts.com (which is a separate company), I see a few options they give for a 1980 C10, with diameters ranging from 1 3/8" to 1 3/4". The ones you have are 1 3/8". Since they don't have a ton of play (or you don't mention it), I suspect you need 1 1/2", part 3.2124. I wouldn't have expected a different width, though.

They are about 1/16" too wide on each side. Got off the phone with Energy Suspension customer service and apparently I ordered the bushings for the shackles. Which BTW are the only bushings listed for leaf springs for my 80 C10.

The rep said I needed to order 3.2108 which is the full set of bushings for the springs and shackles.
I told him I only need the set for the springs since I already ordered two sets (8 total bushings) of 3.2126 which I have no need for...I'm installing lowering shackles which already come with poly bushings. He said they only sell them like that.
