Alright guys looking for bump stops for an 05 with air ride suspension. Some of the Gm websites say they have 2 different part numbers a different number for each side. Other’s use the same part number for both sides. Before I order I thought I go here and utilize the knowledge you guys have. Joined a year or 2 ago. Most all my questions are already answered here by Mixman hummers Cali Phil or bronxtech or any other of the guys on this forum. For any of the newbies out there usually the is already here somewhere. There are some very knowledgeable guys here who are very helpful.

 

Sorry hummerz didn’t catch the autocorrect

 

The air ride is keyed as a RPO code ZM6 aka Off Road Susp Pkg marketed as Rear Air Suspension. ZM6 has a bump stop part number GM 15062871 which you can no longer find. Coil Spring trucks (RPO Z83) have a bump stop part number of GM 15057984 which can still be found.

15062871 is a longer bump stop than 15057984; i'm assuming because if fully deflated this will give the air spring more clearance but I am not sure. I suppose you could still use 15057984 but it ride about an inch and half lower on those bump stops. I've never tried it myself.

 

Thank you for the reply kind of let’s me know what I am up against

 

Yes it is the ZM6
