Roof rack from Leitner Designs coming soon

[Xrford]

Awesome rack but 250# load limit isn’t great for tents.

The install document claims the load limit is 150lbs for off-road and 300lbs for on road.

The average weight of an empty roof top tent may already exceed the off road limits, let alone adding the ubiquitous awnings common place in most adventure builds.

Earlier in the feed you see they tell you do not use the Platform Rack is not for Roof Top tents. it talks about Load Bars instead and the kit for tents. See the links I sent earlier. I bet he looking at dynamic load not static load.

Here you go this what you need for a tent instead of the rack.
Load Bars

Tent Brackets

Awning Bracket ( Optional, but I figured if you getting tent you get Awning as well )

Note we really should have two separate threads for Leitner Design one for Platform Rack, and second for Load Bars and setting up Tent and other stuff on the load bars. I went with Rack since I not putting tent on my vehicle.

Both install docs for the platform rack and load bars have the same load limits, so not quite sure of your point?

I would talk to them, to see what load ratting really is, since that look more like 600 lbs over four load bars 300 lbs offroad. Since documentation is for two load bars your showing above you want four load bar for tent


From the Ineos Grenadier Manual for the Ineos RHINO rack limits so you have comparison

ROOF LOADING
The full length INEOS Roof Rack accessory (not including its own weight) can accommodate up to 330 lb. (150 kg.) of the remaining cargo capacity while driving and up to 925 lb. (420 kg.) while parked. Why the difference? When you are camping, you may wish to move cargo from the cargo area to the roof.When driving, loads placed on the roof exert a high roll force on the vehicle due to their distance from the center of gravity. Loads greater than 330 lb reduces handling and stability beyond safe limits.

The capacities of the 6-foot INEOS roof rack accessory are lower: 264 lb. (120 kg.) when driving and 826 lb. (375 kg.) when parked.
Only INEOS Roof Rack/Roof Bars accessories are designed to be fixed to the drain gutter.

For those inquiring earlier in the thread; Leitner does indeed allow pickups. I picked mine up last week. Those close early on Friday (12PM).

Ya unfortunately, that’s not usually how it works. Doubling the load bars does not equate to doubling the load capacity. For example the platform rack has double the cross/load bars and roof mounting points of the 2 load bar product but yet they have the same max load ratings. Adding more load bars and mounting points, usually just evens out the load distribution and supports the tent/load better.

As I said talk to designer, they tell if what in Manual is Static or Dynamic load support. I agree when you add more bar you reduce the load of what is being bared per Bar. Aka if I had 300 LB on car, two bar have 150 Lb per contact point, now when you go to 4 bar there is distribution of LBs ( force) per contact point but it less then 2 bar contact. Note in statics this is continuous beam problem. Now the roof has maximum load limit before fatigues. what in Manual Static for Rhino rack is ~ 900lbs. What Static limit is since tent 180-300 lbs, put two big humans in the test your now 450lbs for humans + 200lbs tent + 20 lbs for other stuff you need 670 lbs static load support. So I have feeling it much higher then we thinking above for static support, just need to below dynamics load numbers.

Thought I’d update now that I’ve installed the load bars. I went with 3 bars (figured I could always order another if I felt the need. The install is very straightforward and easy. Did a test fit with my iKamper to see if I could lower it down onto the racks and drive right out. Juuuusst barely fit under the door but it works! Still need to attach the permanent quick connect mounts for the tent.

Very impressed with the load bars and I’d recommend them for anyone looking for another option.

Hi DaBull. Thank you for the additional details and your first-hand impression, much appreciated. I've emailed Leitner to enquire about shipping to Australia. One last question. I can find a weight of 60Lbs for the tray but is there a quoted total weight including the mounting brackets anywhere?

I’m certainly curious about shipping one of these to Australia too. Any response from their team yet?

I was quoted $740 USD, they also suggested they are working on a distributor for Australia.

I have one in Australia now. Love it. Shipping not cheap as mentioned but great quality and low profile.

Does it create much noise at 110-120 kph?

 

[K.M]

Does it create much noise at 110-120 kph?

I definitely get a steady whistle starting around 75mph/120kph. It's an awesome rack, though.

 

[MarkIGTM]

Does it create much noise at 110-120 kph?

I haven't noticed any significant increase in noise over no rack tbh. I did get a slight whistle once but seemed to be a combination of wind direction and speed about 80kph. So far only happened once and I've done reasonable hours at freeway speeds.

Maybe someone can validate my recollection, but I thought I remember reading one of the 1st Grenadier installs posted on here that shortly after his install, Leitner proactively reached out and offered a foil/scoop/fin that installs on the front to prevent whistle or wind noise?

Hi Hill Country TX, You are correct. Bernand, who owns Leitner Designs, added a small wind noise reducer strip to the Leitner Designs Rack. Below are links to his rack, install directions and a photo showing the strip that I screen shotted from his instructions. DaBull

Yes, they sent me the “Wind Noise Reducer” as @DaBull pointed out after the initial sale. I believe it’s now included with the purchase of the rack.

After attaching it, I was still getting whistling above 70mph. I have a Thule cargo pod direct mounted to the rack and I wasn’t sure if that was the cause of the whistling or if the rack was the continued cause. On long trips, the noise was driving everyone nuts - especially the dogs. I, separately, purchased Leitner’s Wirelok Wire Guide System. The Wirelok Wire Guide System is the “Wind Noise Reducer”. I cut to size a piece to fit the underside T-slot channel of the front facing load bar. One on top (as shown in the assembly instructions) and one on the bottom eliminated the whistling. Now I just have wind noise that I don’t think is any worse than what I had before installing the rack.

My advice would be to add the bottom piece before mounting it to the roof. It was a challenge attaching it with the rack on the roof. The rack is perfect for my needs and I enjoy it so much more without the whistling.
