Sway bar bushings. Why eleventy-nine sizes?

[yeobee]

My 93 Yukon needs end links. Would be more than mildly dumb no to change the sway bar bushings. Parts check reveals numerous bar sizes. Why? For such a basic suspension component this seems very strange.

Bone stock 4x and it appears they've never been touched. Are they stamped somewhere? Maybe a part number or code in the dash? My old english caliper reads 1.15 to 1.2" Now it's clear as mud. Some parts are listed metric, some fractioned inch. I'm stumped to the point of being a little disappointed with GM about this.

Any help appreciated. TIA.

I can't help, but +/- .050" isn't going to matter after you tighten it down and squish the bushings.

Go with urethane bushings.

I just bought these for my lowered 1991 C1500

If you have a 1.25" sway bar (sounds like it's pretty close), it may work for yours.

Actually, here is a link for the 2 sizes, too. Apparently GM offered 2 different sway bars in those Yukons.

I like Poly sway-bar bushings, especially if they have a grease zerk.

End links are the outside 4 piece mini doughnuts. Or some rear links are dog bone shaped. Inner ones are bushings.
Why different sizes? Who knows, just measure them.
Most the parts stores have new poly in skin paks on display.

Use open-end wrenches for best results. Be aware that some bars are metric.

Thanks everybody. I'm going with the Energy Suspension 3.5181G. I'll report back if there is any goofiness.

These parts were correct for this truck. Not a bad job to complete. I did put the links in upside down and cut the bolt flush to the nut. I think that saved alot of frustration and should be irrelevant to its function. It looks like the bushings will be real difficult to grease, so I slopped them up good before installing. Thanks for the help everybody.
