Sway bar size

Did a search and still have questions regarding the size of the sway bars on 1987 IROC-Z28 front & rear?? Also a good source for Poly bushings and are they split for installation? Thanks

Re: Sway bar size

I picked up digital micrometer from Harbor freight for like $10-$15. Thats how i found my sway bar size. Nice tool to have in your collection.

My Sears Craftsman Professional adjustable wrenchs have markings on them for measuring. I verified that my rear sway bar is 24 mm with it. Unfortunately they don't go wide enough to check the front sway bar.



I'd recommend the rear sway bar mounts that TDS sells.

Re: Sway bar size

Unless you have the 1le package, I would guess 35mm front

Re: Sway bar size

My local O'Reillys has some calipers behind the counter. Yours might too. I would just ask to borrow them, run outside and check. They might have been changed by original owner. Or just invest in a decent pair, I find myself using mine for more than I thought I would

No OE 35mm that I'm aware of. My 85 IROC, for what its worth, was a solid 34/24 combo.
