My 2007 LT 4x4 is now 60 days old, and I now have matching creases on my front bumper.

I really like my Avalanche but am disappointed with the clearance.  

I drove 1 time on the beach at BUXTON, NC, and I felt the shocks bottom out as I was on the sand.   When I checked the front, the air damn held up well, but the bumper creased about 6 inches up from the bottom and the paint has cracks at the crease.   Its not very visable.

My wife driving my Avalanche yesterday on a dirt road, did the same thing to the other side of my front bumper.   So now I have matching creases.


Anyone else have this issue, any thoughts on my next course of action?  Lift kit?  Is there replacement bumpers (body cladding type) that are more sturdy?

Saw a crease exactly like that on one in a dealer's lot. 48 miles on it
 
Uggghh?here we go again with ?my LT has ground clearance issues?.? :rolleyes:

There?s a reason GM offers the Z71 OFFROAD package. This argument may have had some validity last year at this time before the Z71 was available, but there?s no excuse now.

No offense intended, but complaining about the ground clearance on a truck that isn?t equipped with an off-road package is like complaining that the wind messes up your hair while driving a convertible.? >:D

a little mean...but you are right, that only the Z71 is designed for "true" offroading.
 
Then I guess that's false advertising by Chevy (from thier website's Avalanche Photo Gallery):

Can RESPECT not be given to fellow cafcna members? ?When a fellow member takes the time to post concerns about the AV, better to sit back, read, learn and relax, why get so upset when fellow members post about the 2007 AV thinking they were getting a truck like AV's were 2002-2006 finds out that there are some real flaws with the redesigned AV's? ?Whats great about cafcna is its a place where fellow members are allowed the freedom to make and post their own opinions.

febod, first WELCOME to cafcna. ?Do some search's there are many posts here saying the exact things you posted. You'll also find several magazine reviews which complain about the exact same thing. ?Some here sadly get upset and feel a cover-up is necessary to defend the AV. ?Most of those getting upset here are the johnny come lately AV owners who never got the opportunity to drive the (IMO) ultimate AV's built during the model 200-2006 model years. ?The 2004 Z71 AV I owned was a completely different animal than the vehicle badged as the 2007 AV's now. ?IMO the 2007 Z71 AV's are not as rugged as the 2004 Z71's. ?From the low front air dam which just about drags the pavement, to the cheap plastic bulbous bumper, to the 2 hour lesson in mechanic's to change a blown head light, and my all time favorite, the general calling (check your manual) 4x4 AV's as off-road able (even tells you how to do so safely) yet when you check your stock tires they are the cheap (and IMO unsafe) Bridgestone HT's (P-metric (passenger car) highway tires) which are prone to hydro-planing and have no place on the road on a full size truck much less being taken off the pavement. ?By the way the Z71 package these days (esp. on the AV) is more a appearance package than anything which makes the AV any more OFF-ROAD ready. ?The 2007 AV was designed for more show and less go than previous model years. ?Sadly with the current design GM is targeting a much different owner than that of the classic AV.

Guess Loyal GM customers are not upset talking about real issues hoping the future brings better designs, designs which take into consideration the wildly popular GMT800, 2002-2006 AV's. ?I'd sure rather GM see's and hear's the voices of it's consumers pointing out problems they need to work on, than to censor the truth about the AV and continue to live in fantasy land, while being RUDE to fellow cafcna members.

Here's the picture which says it all from my '07.? Less than 8" of ground clearance stock is not a good amount for a full size 4 wheel drive truck with a owners manual which tells how to take the vehicle off road.

In high water, conditions that low front air dam doubles as a rudder

In snow conditions that low front air dam doubles as a plow... until it snaps off? :E:

I'll have to be honost. I never even gave the old Avalanche a second look. I fell in love with the looks and the ride of the '07. I will probably never take my Avalanche off-road. I think of mine more as an SUV than a truck TBO.

I think you nailed it right on the head when you stated that the target market is clearly different for the 07 than in prior years.
 
chunkymonkey,

Well said.  The '07 AV is a great vehicle, not taking too much away from it or those that like it better than the 2002-2006 AV's.  When compared to it's heritage is when I start thinking exactly what you said the once truck AV has with the 2007 redesign become much more a SUV.  Instead of following the Silverado forward the AV is now like the Caddy EXT, Tahoe and Suburban.  IMO thats cool, but also like I pointed out with AV's new direction, with it's new customer focus, it's changed it's abilities and functions.

Sure wish the AV with options could still be both,  Thought with the GMT800's the Chevy AV and the Caddy EXT GM had the market well served with Chevy ruggedness (Like a Rock), and Caddy's luxury.

Still think the GMT900 "SUV's" like the AV need more ground clearance since they are well below Chevy's stated clearance numbers in the spec's, no matter which suspension package is on the vehicle.  IMO the front end design of the GMT900 "SUV's" needs work, it no longer say AVALANCHE, it says Chevy SUV.

Has anyone thought of removing the black plastic piece that is below the bumper? I would suspect that would gain 2 or 3 inches right away. Or maybe there is more to it than I thought.
 
That could be a quick and easy solution but GM (also in the manual) says you can take off the lower front air dam when going off road, but be sure to replace the lower front air dam when back on road, something about not having it will effect engine cooling.

I understand that GM said that but it appears that the Southern Comfort Custom ones dont have the black plastic piece.

Mr Smith I believe they cover the whole front bumper and remove the lower dam because of paint getting chipped (I could be wrong)

CavalancheNY Are you sure about this? It's not an easy remove and replace along the side of the road fix? (07 might be different but my 05 was a 45 min job to remove an replace) I believe its for aerodynamics only not cooling?  If your going to go off road alot why not just remove it?
 
Per the owner's manual:

If you think you will need some more ground
clearance at the front of your vehicle, you
can remove the front fascia lower air dam.
The front fascia lower air dam is held in place by
two bolts and 10 snap features. The bolts and
snap features are accessible from underneath the
front fascia.
The following steps must be performed on the
bolts and snap features to remove the air dam:
1. Remove the two outboard air dam bolts.
2. With a flat-blade screwdriver, push down on
the snap features and disengage the snaps.
3. After the bolts are removed and the snaps are
disengaged, push forward on the air dam until
it is free.
When you are back on roads, though, be sure to
replace the air dam.
Notice: Operating your vehicle for extended
periods without the front fascia lower air
dam installed can cause improper air flow to
the engine. Always be sure to replace the front
fascia air dam when you are finished off-road
driving.

To reinstall the lower air dam do the following:
1. Line up the snap features and push the
air dam rearward to engage the snaps.
2. Install the two outboard bolts.
 
The "Off Road Driving" section of our '07 owner manuals which tells how to remove the air damn for off road driving also states:
"Notice: ?Operating you vehicle for extended periods without the front fascia lower air dam installed can cause improper air flow to the engine. ?Always be sure to replace the front fascia air dam when you are finished off-road driving"

BTW here's part one of this topic:

Thanks to Enkei we have Classic AV and '07 profiles....

Monitor temps with it on and then take it off and monitor temps. See if there is a true difference. That should be a pretty simple test.

Dang it, I tol' ya to put air in your tires before you measure the front ground clearance! :p

Seriously though, I'm still not sure how yours ended up so low.? As stated in the far back not-so-agreeable discussion on this topic, my LTZ measures out at 9.5" at the lowest point.? Removing the lower black plastic would put me closer to 12" clearance (assuming there aren't tabs sticking down from the painted portion of the bumper, which there may well be based on other posts around here somewhere).

The Z71 design is a bit better (higher everywhere but in front of the tires).? Still, it'd be nice if a true off-road-friendly package, including heavy-duty non-chromed winch bumpers and a 6" lift were available, just to soothe all those that want to take these vehicles more extreme places.
 
Thanks for all the comments.  

The damage is not bad, and I included pictures here for your viewing pleasure.   I am just disappointed with the clearance, and it did not occur to me to need the Z71 for the occasional drive on the beach or trip to the state fair grounds.

Does anyone know how much a lift kit would cost (I am not very mechanical) installed, would it raise the truck 5 inches??

Again, thanks for the input.

You can't see it with the picture, but the paint now has spider cracks about 5 lines on each side about 2 inches longs.   :(

I'm looking at the Rancho 4" lift myself, mostly to feel a little more comfortable in winter driving up here in the NE (never know when you may need to plow through a snow bank, like if the plow driver buried your truck). The lift itself (w/ skid plates) was going to be around $2,200, a little over $4k installed w/ allignment. Then you have to add wheels/tires. I think the Fabtech 6" lift was in the same neighborhood, maybe a couple hundred more. I have an LTZ (w/ Autoride), but if yours is non-Autoride (5.3L LT/LT2/LT3), you'll have a larger selection of lift kits available.
