My 04 tahoe roof rack cross bars appear to have been broken off prior to me buying it. Does anyone have part numbers of what I'd need to make the cross bars whole again? Trying to stick my canoe and kayaks up there. 20221016_121417.jpg

Do you have any pics of the outside of the rack? My '04 rack has the groove on top. This looks more like it miight be an Esky or Z71 rack but I'm not sure about that. Maybe one of our experts could confirm.

I have a set of crossbars and the clamping ends that might work (the crossbars aren't painted and might be a bit difficult to ship due to the length), but here is one of the four ends that I have. If you have the crossbar pieces, all the better.

If you think they might work, you can have them for the cost of the ride.

Should have clarified better, this is a z71 tahoe, so I'm assuming it's the Z71 rack? Here's an outside pic. Thanks for the offer! If you think they'll work I may take you up on that!

As a side note, I'm missing the back right end cap. Looking on Ebay, only back lefts appear to be available. Do the back rights tend to fly off in the abyss?20221016_144913.jpg

I got my roof racks off my nnbs 07 if my crossbars will work you can have them just pay for the shipping
But depending on weight it might be better to get some thicker Thule or Yakima cross bars to replace them as they are a lot sturdier then the factory bars

Look on Craigslist or FB Marketplace for Tahoe part-out vehicles...
They are not always there, but I have seen some locally. Not everyone knows the Z71 racks or other bits are anything special, so everyone is not always looking for big bucks on random parts.

For example... Here is one in Chester, VT. (Not sure where you are, but there might be something sitting close to home.)

My 04 Tahoe Z71 had no roof rack on it when I bought it last year. I guess the PO was looking more for a low profile/street-performance look with 285/45 R20 tires and no roof rack.
I was fortunate one of our forum members had the entire rack in his garage in FL. I was interested in buying it, but shipping was going to be a couple hundred bucks. I didn't need it right away. He was willing to drive it home from FL when he came back in the spring, then even helped me get it all mounted! That couldn't have worked out any better! He sold the rack he was sitting on for 3 years and I got something I could actually afford. Members here are super-nice, helpful and generous!

Note: While other crossbars may fit the slots... Z71 Crossbars and side rails are quite a bit heavier than what is on the LT or other trim packages. In your case, the weak point that broke was the crossbar end. They are also pretty beefy, so there must have been a pretty heavy load tossed up there to snap it off at the end like that. You'll want to see if you can get bits off another Z71 rack, if you can.

Thanks for all the help. I got to wonder what happened to rip them off there like that. Luckily there is no other damage that I can tell.

The Z71 side rails are super stout.

A post here, says the side rails can handle up to 1,000 lbs...

Crossbars are rated for 200 lbs. according to my owner's manual. It can probably handle more and I am sure many people have loaded more than 200 lbs., but GM has to have the lawyers cover the engineers' butts from lawsuits.

Spreading the load would allow more capacity. Extra crossbars would likely increase the weight you could load on there by spreading the load over more bars and transferring the load onto the side rails.

Your broken end brackets on your crossbars were probably carrying much more than 200 lbs., as we were suspecting from the beginning and that the load might not have been evenly distributed.

From my 2004 Tahoe manual...

Luggage Carrier
If you have the luggage carrier, you can load things on
top of your vehicle.
The luggage carrier has slats and siderails attached to
the roof and crossrails which can be moved back
and forth to help secure cargo. Tie the load to the
siderails or siderail supports.
Notice: Loading cargo on the luggage carrier that
weighs more than 200 lbs. (918 kg) or hangs
over the rear or sides of the vehicle may damage
your vehicle. Load cargo so that it rests on the slats
as far forward as possible and against the side
rails, making sure to fasten it securely.
Don’t exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, see ′′Loading Your Vehicle′′.
2-57

To prevent damage or loss of cargo as you’re leaving,
check now and then to make sure the luggage and
cargo are still securely fastened.
Be sure the cargo is properly loaded.
• If small heavy objects are placed on the roof, place
the load in the area over the rear wheels (behind
the rear side door on Suburban Models). If you
need to, cut a piece of 3/8 inch plywood to fit inside
the crossrails and siderails to spread the load.
If plywood is used, tie it to the siderail supports.
• Tie the load to the crossrails or the siderail supports.
Use the crossrails only to keep the load from sliding.
To move the crossrails, pull out on the latch release
handle at each end. Slide the crossrail to the desired
position balancing the force side to side. Push the
release handle back into the latched position and
slide the crossrail back and forth slightly to be sure
the latch snaps securely into place.
• If you need to carry long items, move the crossrails
as far apart as they will go. Tie the load to the
crossrails and the siderails or siderail supports.
Also tie the load to the bumpers. Do not tie the load
so tightly that the crossrails or siderails are damaged.
• After moving a crossrail, be sure it is securely locked
into the siderail.

Your vehicle has a Center High-Mounted Stoplamp
(CHMSL) located above the glass or above the rear
load doors.
If items are loaded on the roof of the vehicle, care
should be taken not to block or damage the CHMSL unit.

If your vehicle has the Z71 option your vehicle’s
luggage carrier has a roller crossrail at the rear of
the vehicle.
To load cargo, place cargo on the roller and roll the
cargo forward onto the two front crossrails.
To move the crossrails do the following:
1. Loosen the thumbscrew at each end.
2. Move crossrail to desired position.
3. Tighten the thumbscrews.
Make sure the crossrail is secured.
