Just browsing through my stash of junk.... I have a 7/8" poly sway bar bushings part number 5.5113G . Those fit in the factory narrow U straps I have. That's a factory sway bar diameter.
Now question is, do that make a 1 1/4" diameter narrow bushing version that fits the narrow U straps? I can't find them, maybe call energy to see if they make such a thing.
