I have an 08 rcsb 2wd Z71. Can anyone tell me what the difference in suspension parts is on this truck vs a standard rcsb v8. Found nothing in the RPO codes besides the Z71 package. It seems to sit extremely high compared to other 4x4 z71's, and especially against other 2wd trucks (About 2.25 inches). I have leveled the truck with 2 inch drop shackles and added a hellwig 7800, I have looked all over the suspension for aftermarket lift parts and found nothing but stock parts. I am looking into lowering the truck but at this height a 2/4 drop would put me at stock height of most other rcsb's.

 

Probably just shocks and skid plates.

 

Bingo.

 

Did you buy the truck used? could be that the previous guy lifted it of used it to tow and put lift blocks in the back? Ive seen this a few times on trucks that my buddy's have bought.

 

I did buy the truck used, but I have not found any signs of a body or suspension lift.

I know that the Z71 upgraded the shocks and added skid plates. But I cant imagine the stiffer shocks raising the ride height. here is a pic of the truck before it was leveled and the sway bar added.

it looks low to me, but all my trucks are lifted. Check for larger blocks and strut spacers (on top of the strut), or the spacers under the strut.

 

Thanks crawford, found blocks under the strut. Found my culprit, I am going too wait and remove them when I replace the stock struts with rancho rs9000xl's.
