I have a 2001 Silverado 2500 4x4, ECSB, towing package etc. What comes in the Z71 package that I don't have, that I might want?? And, are there after market equals that are better than OEM (Z71) ...? Any other info that might be helpful, such as OEM part numbers, etc ... Thanks!

 

the only thing you might want is the skid plates.

The z-71 package comes with a locker, (****) shocks (not even close to the best) a sticker, and skid plates.

 

and a chrome rear bumper is standard on z71s, optional on 4x4s...

 

stickers,shocks,skid plates like above

 

Also Jounce spacers and different sway bar on the new trucks (not sure on the GMT-800s.

 

not all Z71s have a G80 (locker) my 99 did not

 

LOL, when I first bought my truck I was so stoked that it was a Z71, now the only thing from the Z71 package that's left on it is the skid plates

 

I still have my skidplates.....AND my G80.....lol!

 

that sway bar on the nnbs makes a night and day difference between the 4x4 and z71, 4x4 handles like **** compared to the z71

 

On the previous body style trucks, the Z71 RPO option usually just consisted of the metal Skid Plates, Diffrent Shocks, 2 Bedside Decals and yes, they should have a Limited Slip Differential.
