Ok i was looking on GMPD for the rear inner Bushings for my new FE2 sway
and....

They have a 17mm one listed and a 21mm one.

Now i though there was only a 10mm (FE1) and a 18mm (FE2)

17mm: Std Susp Bar, Stabilizer 25559835
21mm: Sport Susp Bar, Stabilizer 25559836

any ideas whats going on here :?

also if someoen has the part # for the rear bushings that would be Great

Heres what mine is

21mm is F41, never heard of 17mm...

i think thats wrong.
Cuz on GM PD there are only Two Sway bar types 17mm and 21mm

and my new front is 32mm

are we taking rear or Front

there NEVER was a 10mm

and FE2 and F41 share the same Sway bars

Okay... your front is F41 too.


GMPD often "loses" parts and clumps them all together. No point in stocking 47 different sway bars for a fifteen year old grandpa car.

But far as the other numbers, im going off what others have told me.

Now that im doing research before i buy now, im finding out diffrent stuff

Dame....F41 and FE2 share the same sway bar the only differences are the spring rates to make the different suspension

17mm and 21mm are accurate for the sizes of the sway bar

17 is FE1 and 21 is FE2/F41

simple as that for the rear

I know this. I was one of the very first to swap these parts, You seem to have forgotten that. I also put a lot of track time into my testing and base my opinions on these swaps on that, Not just some book and some spirited driving around. In case you're wondering, You have infact pissed me off.
