    What’s Included

    Made in USA
    Machined in-house from black anodized aluminum

    Before Ordering

    1. Measure your rack or crossbar
    Use calipers or our printable measurement tool if it is round tubing to confirm your tube diameter before selecting a size.
    2. Confirm your tent hardware
    These mounts are designed for tents that use standard aluminum mounting tracks with 5/16-18 or M8 hex head bolts. Most tents include aluminum slider nuts that work with this style of mount.
    3. Select the matching mount size
    Choose the size that matches your actual tubing or crossbar dimensions. These mounts are oversized slightly to help accommodate powder coating, but thicker coatings or unusual rack profiles may require sanding, filing, or modification.
    4. Choose your quantity
    For heavier or more expensive tents, we recommend the 6 pack over the standard 4 pack. Your specific rack and tent rail layout may also limit how many mounts can be used.

    Installation

    1. Position the tent and mounts
    Place the mounts around your rack crossbars and align them with the aluminum mounting rails under your roof top tent.
    2. Start the hardware
    Start by tightening one bolt with a 1/2" socket or box wrench, then alternate between bolts so the mount tightens evenly around the crossbar.
    3. Maintain an even gap
    These mounts are designed with a small gap between the top of your tubing and the top of the mount. Tighten evenly and do not over-tighten. The gap should be no less than approximately 0.080" when installed.
    4. Check after installation
    Confirm the mounts are snug after a test drive or two. For added safety, inspect them again before long trips.

    Installing a roof top tent can be challenging due to the size and weight of the tent. If you are lifting the tent or installing it for the first time, we recommend having 2-3 people help with installation.

    Good quality

    I got these for my Topoak Stellar tent and my Venom roof rack for my 4 Runner and they are way better than the stock brackets that came with the RTT. These do not bend. They fit very nice.

    Perfect addition to my Roofnest

    Purchased the 1x2 mounts to attaché my Roofnest Falcon CL to my Prinsu rack. Perfect fit, so secure! Really what these tens should come with standard considering the price tag.

    Perfect solution for an adventure

    Am thankful to have found a site that sold exactly what I needed. Had put my rtt on top of my rack and realized that the brackets I had weren't going to work. Was able to find them here and contacted support and they were quick to get back to me about next day delivery. Super helpful and I'm glad I was able to go camping the next day like I planned.

    Perfect fit for Prinsu bars!

    These mounts are very well built and so much more secure than the universal stock hardware that came with my tent. Those generic mounts are made for the standard wing shaped rails that comes with most SUV 2-rail system.

    The GZila fits my rectangular 1x3” Prinsu rack bars perfectly! Also the KEPS locknuts that comes with these GZila mounts are much higher quality than standard nylon locknuts and unlike the nylons, you can turn them by hand up to where it’s flushed against the mount and then you tighten with ratchet. I’ve attached both for comparison.

    Just what I was looking for!

    We have a Jeep JKU with a Gobe Stealth rack. I have been wanting to install Thule Hullavators for a while now. The Hullavator requires a load bar that extends beyond the rack 4 to 8 inches. While planning how to accomplish this...I envisioned a bracket that would allow me to mount a commercially available load bar to the 1” diameter top tube of the Gobe rack. Somehow...I tripped across G-Zila Designs website. Eureka!!! That’s exactly what I was looking for. Soon, I will attach two Thule Wingbar EVO 150’s to my Gobe Rack using the G-Ziika Tent platform mounts for 1” dia tubing.

    I am very impressed with the G-Zilla production work on these brackets. Very tight tolerances. Excellent post production finish applied. This product is not only structurally well engineered...but aesthetically pleasing as well. Once the load bars are affixed...the Hullavators will be mounted...and I will have a load assist Kayak racking system in our Jeep. No more bench pressing a 17’ and 16’ Kayak over my head.

    Excellent Solution!

    I had been looking for some kind of mount for my tent and was having quite a hard time finding something that would work with my bed rack which I had fabricated. When I found these mounts fit 1.75" tube, I was sold immediately and have been extremely pleased! The fit and finish is fantastic, and install was a breeze. Highly recommended.

    Perfect solution

    Finally, a perfectly elegant solution to securing my expensive RTT investment! These mounts are well made and very easy to install. They look 100% better than the oem mounts and the theft deterrent caps are a huge plus.

    Perfection

    These mounts are what a rooftop tent should come with. My tent weighs over 200 lbs, so the cheap hardware that it comes with always made nervous that something could happen while traveling. These give you that peace of mind that your expensive tent will be perfectly secured to your rack.

    Eased my mind

    These RTT mounts are exactly what should be included in your hardware kit when purchasing your tent. The fit is perfect and snug. I bought my new RTT last summer and almost lost my tent down a 100 foot drop off 3 hours after install because the original mounts and hardware was junk. The original mounts slid side to side on my bed bars from Relentless Fab and led to the powder coating being rubbed off and some rust. My mind is at ease now with these new mounts!!! Im very excited.

    Have been struggling with keeping our Mt Hood Cvt mounted securely to our Gamivitti rack with the hardware provided. The rtt would shift side to side while out wheeling and would have to add just many times during trip. Received the 1” mounts and threw them on . All I can say is well worth it and a must have . Will be changing all other rtt mounts to the Gzila mounts

    Best RTT mounts on the market

    I’ve had 3 roof top tents with different brackets for each. Most just give you the universal mounts for all racks. I wasn’t happy with the ones I received and started looking for other options and came across these mounts. I originally order a set of 6, 4 for my tent and 2 for my 7 gallon shower. I wanted my tent to be a little more stable and just the extra peace of mind so I added 2 more on the tent just to make sure it doesn’t go anywhere. These mounts are solid and I have zero worry of them breaking or coming loose. I wish I would have found these years ago when I bought my first RTT. Fast shipping also. They are pricey, but you defiantly get what you pay for.

    Square bar rooftop tent mounts

    This is a great solution for those who have square bars and need to mount a rooftop tent.

    I tried looking all over the place as the stock mounts were nowhere close to secure. While these are on the pricey side, they worked great so I can't complain.

    These are stated to work with THULE but also worked with my INNO racks which use the same size bar. It's slightly larger than the Thule due to the coating on the inno but will still work.

    Amazing mounts!

    Replaced my OEM tent mounts that we weak and flimsy, always squeaky. These are solid and have solved all the issues I had. Money well spent
