Cross bars for gamiviti racks and gamiviti towers
We can help you resolve most every roof-mounted challenge by providing one of three options for roof cross bars. The options are as follows:
Extruded cross bars: This is the most versatile solution, these work when paired to any Gamiviti tower for a cross-bar only solution, and they can also be added to a Gamiviti rack. They can be mounted onto Gamiviti towers, Gamiviti racks, or Multi Brackets on OEM rails.
Welded cross bars: These custom steel cross bars are custom made to fit your Gamiviti rack. The default width is 50” but they can come in variable lengths as you specify. These are not in stock, they are made to order, most commonly at the same time as we are building your rack but we can also make them for you later.
Rhino cross bars: For those that prefer the look and functionality of the Rhino heavy duty bars, we can also offer these to you. They can be mounted directly to Gamiviti towers, or on top of your Gamiviti rack.
Extrusion cross bars
The extrusion cross bars are available in 2 sizes; 40mm t-slot profile, and 1x2” t-slot profile, both available in a 60” or 52” width. In general the 60” length is a good starting point for 60 series Land Cruisers, or other setups where you want wider cross bars, where the 52” length is closer to the vehicle width of 80 and 100 series Cruisers, as well as the 4Runner and GX models. The cross bars are easily trimmed to length using your own chop saw, or you can contact us for a custom length.
Two different hardware kits are available for the 40mm extrusions; one for securing cross bars to Gamiviti towers, the other for securing cross bars to Gamiviti racks. The square 40mm extrusions are the stiffest of the two, and they can take 5/16” carriage bolts for easily securing to towers, or adding accessories. The 1x2 extrusions are the same stuff all of the extrusion racks are made from, they are lower profile and require track nuts for mounting and adding accessories.
Uses of extrusion cross bars include…
Create a “quick release” system with 40mm extrusions, making it easier to mount your roof top tent on your Gamiviti rack. The cross bars mount to your tent, then you secure them to the rack plates using the threaded knobs… to remove the tent, just remove the threaded knobs and lift.
Create a support for your roof tent lift system. If you have a Racor, Fleximount, or other lift system in your garage for raising and storing your RTT, you simply loop those cables around the ends of these extrusions to lift it.
Create a side rail to secure loads on your rack using 40mm extrusions. These extrusion cross bars can mount both across the rack, or lengthwise.
Mount cross bars directly to Gamiviti towers- for light duty applications where a full rack isn’t required, or if you’re waiting for your full rack to be built, you can use these cross bars on your Gamiviti towers to get you by and out the door.
Mount cross bars to Multi Brackets- for even more versatility, you can mount these extrusion cross bars to our Multi Brackets, providing a more raised cross bar system on your Gamiviti rack, or using the Multi brackets on a trailer. This allows you a fast solution to transfer a roof tent between your roof rack and offroad trailer, for example.
Below are a some pictures that show you these installed.

Welded Cross Bars
Custom-made, bolt-on cross bars provide a new set of accessory mounting options. These bars bolt directly to the plates of your Gamiviti rack, using the same matching stainless hardware, and stand about 3" above the top plane of your rack. Some of the uses and advantages to adding cross bars include...
Allow for the installation of rooftop tents on racks that run the Expo bar "up." These bars allow the RTT to open over the top of the Expo bar.
Allow for installation of some aftermarket accessories that require the accessory to extend below the top plane of the rack, including some bike racks and cargo boxes.
Provide a space below a RTT for storage of smaller items. This is even more useful on racks where a drop-down basket has been added.
Serve as an easier tie-down option for some boats and kayaks, where it's advantagous to have them raised slightly above the main rack plane.
Transition the installation of a RTT from under the RTT, to outside the tent, where it's much easier to manipulate the nuts and bolts.
When left on the RTT, provide an easier means to carry and hang the RTT in storage.
Cross bars ship for free with your roof rack, which is also the fastest way to get them as they are custom-built to fit your specific rack width. Custom heights are also available.
Rhino heavy duty cross bars
For setups where a full roof rack is not available or desired, it’s also possible to use Gamiviti rain rutter towers and Gamiviti roof channel towers paired with aftermarket cross bars to create a custom cross bar system. One easy solution is the 50” Heavy Duty cross bar from Rhino. This is the ideal width for most Land Cruiser applications and is a direct bolt-up to our towers, they also work when paired to our Multi-Brackets for adding a raised cross bar to your Gamiviti roof rack.
To install the cross bars to you Gamiviti towers, you’re going to want to get some 3/8” channel nuts from the hardware store, found in the aisle where they sell uni-strut and electrical conduit. We recommend the channel nuts with springs, as they stay in place while you line up your tower and bolts, and we’ve put together a complete hardware package with stainless bolts that match your towers, found below. You can purchase your own hardware, or select a hardware kit below to match your cross bar selection, one cross bar will take 4 channel nuts, 4 bolts, 4 washers, and 4 lock washers. This hardware kit also works when installing Rhino Pioneer platforms to Gamiviti towers.
