This being a uni-body I noticed a square rail on the drivers side that you can see mounted below the body.

It is 1X2" rectangular, runs from the front to the back with 4-5 mounts but is a couple of inches below the body. I think it is to protect the fuel tank. IE to bottom out instead of punching the tank.

The passenger side does not have this, but there 4 1/2" steel lines that run to the back. These are lind of exposed.

I guess without a frame to run these lines through they just hang them out there.

I have noticed that too.... but I also noticed on the Saturn Outlook - the XE and XR with the 18" wheels had them on both sides. The touring package - 19" wheels only had it on the drivers side.

Anyone without the 19" wheels care to check this out on an Acadia?

Interesting! I do[/color]have the bar on both sides. I have the 18 inch wheels. The running boards (which I have) also protect the steel tubing that you were talking about.

 

[mitchl]

why would they make a change like that because of tire size? Does everyone correlate to just that being the variable, or could it possibly be because of build date?

 

[sandman]

That is a really good question. You may want to post this in the general forum where everybody can see it. I'm not sure all read the teck section.

And the general says.......
(1-19-2007)
Condition/Concern: The Right underbody side rail is missing from the factory or the parts department is unable to locate a replacement part in the catalog. If comparing this to another identical vehicle, some early built vehicle had the underbody side rail on both sides. At this time there has been a design change and this part is no longer used on the right side. The underbody side rail is not a structural part of the vehicle.

Hmmm... But nothing definitive about it's purpose. Would be interesting to know what these were for in the first place.

Hey, its finally nice to hear that besides getting all those recalls, I also got something else (the right underbody side rail), that all you ole late comers didn't get. ;D

I wondered about the underbody rail on the driver's side of my wife's 2011 Acadia - it is for cosmetic purposes only per this link. /cgi-bin/mt/mt-search.cgi?search=TAC&IncludeBlogs=10&limit=19&page=12

Would love to see the link, but what does this link to. Don't we need a web page or something?

Newbies must post either five or ten times before being able to link anything :shrug:

Yes, I can't post links yet. If you add a "dubya dubya dubya" "sandyblogs" "dotcom" in front of the link above you should get to a GM Tech Links document. Scroll down and you'll see the discussion about the underbody side rails.

If anyone is interested in some extracurricular reading, there are other tidbits about GM products included within the page. I disagree with the statement that the rail is purely 'cosmetic.' It might help keep 'curb-hoppers' from ripping apart the fuel tank!

Interesting link, thanks. By the way, I tend to agree with Speleos. I have done enough off road stuff in the Sierras, that I do think they give a slight bit of protection. Added note. I recently cut a parking lot divider too close and knocked my running board loose. Had to take off the brackets and rebend them in a bench vise. Basically, good as new.
