i got you, mang.

Coulda sworn my GMPP was the exact same size as stock but just solid instead of hollow.

I believe the front gmpp is solid, the weight difference is significant over a stock one

fail matt, fail.

So does anyone know for sure if the front GMPP is solid or hollow? Seems weird that they would go from hollow rear to solid rear but leave the front hollow.... But then again the front increases 6mm and the rear only increases 2mm so maybe thats why....

you're fail, those links didn't tell me what the stock size is.

I kno hes right on the size, I had a hell of a time finding a poly bushing at the time that would fit it

why dont u measure it then?

because its cold outside and i dont have a caliper?

Any different for 04+? How about Comp G/GXP?

with 04+ if i remember correctly u need 97-03 LCA's in order to mount the front aftermarket swaybars. otherwise i think theyre the same, comp g's might have them bigger, not sure. gxp's also a different ball game.

how difficult is it to install the front sway

I second this ???

not that difficult. hardest part is wiggling it in and out, unbolting and bolting it back in is cake.

Someone should add which ones we can pull out of a junkyard for an upgrade. If I remember correctly some of the other W-body cars came with the GMPP bar...Impala, Monte Carlo?

any cop car had the gmpp stuff on it.
