Question, if I'm driving around 40 and happen to hit a Tennessee bump in the road the rear will bounce and sounds like it bottoms out and hits something.
I haven't noticed excessive bounce like worn out shocks and shocks are not leaking that I can tell.

Any suggestions?

Springs support the weight, the shocks dampen the bounce. I would look at the shocks first. Also look at the rear stabilizer bar and see if the bushings are showing wearing in it.

Thanks, I'll get under there and check the bushing

Hey Butch06 when your under there check out your bump stops they might be deteriorated to the point where they are not working. Had a bad one on my 04 with only 35,000 miles on it, not that expensive to replace.

Hello,
Does anyone know the correct replacement rear shocks for a 2005 with manual trans. GM p/n 15209863
One website said the auto trans P/N is different. These are Bilstein shocks with the number "A9E" on them.
Thanks

I think that Mike at Simple Engineering may have them.

Yes, I have a pair of the original 15209863 shocks in the OEM boxes. Yes, they are only for the 6-speed SSR. I do have a very suitable, more generic, Bilstein replacement available in my web store. The replacements in my web store have a fatter body with very nice damping. They work well with both the automatics and 6-speed axles. I will sell the OEM ones to you if you MUST have them. They are $150 each, plus shipping.

For those that wonder..... The reason GM created the ones for the 6 speed is because of the difference in unsprung weight....... the rear axle for the 6-speed truck weighs about 80 pounds more than the Torsen axle in the automatics.
