If anyone should know this, I would appreciate the information.

Apparently, having an SS in 2001 doesn't necessarily mean that the SLP suspension was installed, that was an "SS" option, and the original owner did not order it when he bought it. So, based on the window sticker & RPO codes, I have the "FE4" suspension...

Great, so what does the FE4 suspension come with?
The window sticker says that it came with the:

"HI PERF. RIDE & HANDLING SUSP."

Okay, so what exactly does THAT mean??? Based on the wheelwell space I would ASSUME that the shocks & springs are factory stock, but what about the swaybars???

Anyone out there able to enlighten me?

P.S. I called the dealership regarding this, I spoke to the manager, I gave him the VIN code, he said he will get back to me, unfortunately that was 3 weeks ago.

 

32mm/19mm both hollow

 

For the "HI PERF. RIDE & HANDLING SUSP.", model year 2001, GM replaces the 30 mm from bar with a 32 mm bar; the rear stays the same at 19 mm (all hollow).
