Does anyone know if this would work if you only have cross bars and no side rails?

Yes, is possible to use the straps only with cross bars, but of course you have to tight hard and pay attentiont that the unit´s botton is not rubberized.

They will clamp on to just about any roof rails but if the roof rails are more than 48 inches apart from each other these cross bars will not work.

You might check their website. I had cross bars on my roof rack and they mounted no problem.

You will need a front riser so you do not feel you are going over the handle bars. I am sure you can make something up but I bought one since I knew it would work and it would be level.

As long as your crossbars are adjustable. This is a nice box for the money, but the attachment points are somewhat fixed.

I think it wants/needs perpendicular rails on all four sides. There are 8 connecting straps, 2 per side. With only crossbars, it might slide to one side or the other.

Probably could bolt the side rails together. I did not like this product - very cheaply made.

Yes, the cross bars can slide within the upright pieces. As long as the trailer has angle iron rails, it will work.

I have side luggage racks so I am not positive if it will cause an issue with no racks.

Yes. I have managed to load mountain bikes, road bikes, kids bikes (of various sizes) and a women's bike with no cross bar. Worse case scenario is you can get a cross bar attachment like this one: Allen Sports Tension Bar Bicycle Cross-Bar Adaptor

There are actually two sets of mounts to allow the rack to work on more that one style of cross member - it's extrememly versatile. I have a 2014 Subaru Outback and they work fantastic. I drove 5 hours one way, mostly high speed interstate but also hilly curvy small hwy road - performed flawlesly. If your cross members have a bow to them, you will want to mount the rack in the middle if it's improtant that you have your bike perfectly upright. if its flat, the side is fine. good luck

Car came with roof rack but without cross bars. My guess is that it's a dealer only item and you probably want thenm to install it also.

I wouldn't risk it - depends on the length of the crossbar compared to the distance from the rear window to the back edge of the trunk - too long a crossbar might leave the top tube resting on the trunk rear edge. Too short might mean the bike seat sits in the middle of the trunk with the bike weight acting on it. With a flat backed car (station wagon or SUV) the bike hangs down with most of its weight supported on the cups and very little weight on the body work of the car. It is a great system if it fits - first use is a bit of a leap of faith though.....expensive bike held on by suction!

Same as the others. You need to install on the cross bars not the side rails.

I believe the side rails you are referring to are the rails that run the length of the roof. Those rails usually come standard on the LTZ model. Make sure the metal inserts are in the rails that are there now. If not, you'll have to purchase those. If they are there, then this set of cross rails will work.

Would only recommend straight bar frames with this product. A two arm style rack would work much better for a slant bar frame.

If those crossbars are adjustable I would say yes. I mounted this on my toyota 4runner and my factory rails are adjustable. What is this going on and I can help you out a lot better.
