came across this today while looking for new sway bar u-bolts and spacer to replace the old stuff.
its a dorman 22.2mm rear sway bar:

any one seen this before? i couldnt find a single mention of it anywhere on this site or google for that matter. just curious.

 

I called Dorman 3 weeks ago on this bar and was told it’s actually 19mm. I know the website says 22 but there is a mention of 19 which is why I called.
I’d love for someone to actually measure one and find out which it is.

 

You are right. The Doorman site only mentions 19mm. I just checked Amazon and they say 22.2mm. weird, someone is probably messing up cuz 22.2 sounds like a random number.

 

Perhaps the bare bar is 19mm, and the paint coating is 1.6mm thick?

 

Perhaps. But that would be a lot of paint.

 

is the stock bar 19 ?

 

and still not 22.2 mm 😄

 

yes, stock rear for v8. V6 might be different.

 

Yes, 19 mm is stock but at some point I believe there was a 22 mm option from the factory which is why it possibly made sense that Dorman would make a 22 mm.

 

There was never a 22mm from GM. There was a 21mm and it was not on a lot of cars. There was a 23mm on 3rd gens too, some but not many.

 

yup, from what ive read, the 21mm came on cars with 1LE suspension. Who knows what Dorman is thinking.

 

And only in 1993. 94+had the 19mm. The only exception were the Bilstein ultra suspension cars The last two years. Those cars also had 21 mm rear bars.
