I need new rear shocks for my 2003 Yukon Denali AWD and I’ve been told they’re pricey. I bought the vehicle used and can not tell from looking at it or the paperwork I still have whether the suspension is ZW7 or Z55 and the difference may mean $100/shock. Is there any way to tell from looking at the vehicle? ---

Ask a dealer to look up the spec sheet using your VIN number. ---

Search for you RPO list,probably on glove box door see if it has these codes. ---

The RPO list worked! It was on the glove box door and said “Z55”, no sign of ZW7. (Though I may still call my local dealer just to verify.) Thanks all!
