Xj XJ roof rack supports

Hi there jeep world. I have a roof rack on my jeep its mounted to the factory cross members with some rubber clamps it came with. The factory cross members are so flimsy when I have my spare loaded and hit bumps I can hear hit the roof. Do they make any heavy duty cross supports? Iv seen the gutter mounts just not sure how they would mount to my rack. Maybe if anyone has any pics or some experience with similar issue that be great thanks.

Ill try to get a pic to but some eyes on my question

Look for gutter mount cross bars (Thule etal) which will likely be stronger & higher from the roof than the OEM rack.

You could get a couple more factory crossbars from the boneyard and cut the load in half that's on each one underneath the basket.
Are you sure something is hitting the roof and not just the tire or basket bouncing on the crossbars? Something actually hitting the roof would leave a mark.

Get a mount that doesn't mount onto the cross members but the rails those are mounted on too, that's how mine is mounted and it is stout.

Hey guys thanks for the reply's. I assume its the rack hitting the roof, never thought maybe the tire bouncing around. I just have a ratchet strap on it.

The factory bars are MEANT to give a little. They're kind of elastic and push up against the load along with acting as sorta shock absorbers to keep the full force a bump from hitting the flimsy roof all at once. If you don't have a scratch or a dent, then I'm with Chris it's probably just stuff bouncing a bit. on the rack, or the rack mounts popping when the bars flex.

As for gutter supports, they can hold a big load.
Maybe this will give you an idea.

I keep wondering how that doesn't bend the gutter down. It's still just sheet metal.

I'm not a structural engineer, but it looks like the horizontal metal that it sits
on is double-thickness, brazed or welded together. With eight support points,
the load is widely distributed. The rack is very rigid, so the load doesn't
bounce up and down on any one place.

After six or seven years the original green gutter moldings got bent up, but that
was mostly due to the original clamps which were not so well-fitting as the
ones on there now. The horizontal surface the rack rests on never really was
bent.

I got rust mostly on the underside of the horizontal surface, not on the top.
The welder patched in sheet metal on the underside, painted it, then attached
the black gutter moldings.
