Added these to my Inno BRM660 roof box for a quieter ride. The Inno t-slot inserts worked in my Thule Aero bars easily. My only complaint is that in order to maximize storage space, the strap loops must be mounted to the outside, which causes extra friction on the strap, making it slightly more difficult to tighten easily. This is a very minor problem, but the only one I can come up with. The extra quiet is worth the extra effort.

I bought my carrier from Sears long ago and thought it was useless now since the key went missing years ago. So happy I found this site, and the right replacement key. I received when promised and it works!! Thank you!

2018 Tesla Model 3 Accessories And Parts Questions

• Best Cargo Box for 2018 Tesla Model 3 with Least Amount of Front Overhang
  
• I have the perfect cargo box for your in the Inno Wedge 660 Rooftop Cargo Box part # INBRM660WH. I went out to our warehouse for you and measured from the center of the forward-most mounting clamp while slide to the front of the box to the front edge of the box and came back with only 18". Therefore, the Inno Wedge 660 will not have near as much overhang as the Yakima RocketBox Pro 11 Rooftop Cargo Box that you have now. The Inno Wedge 660 also has a much more aerodynamic design...

• Will the Thule Force XT XXL # TH6359B Fit on my Tesla Model 3?
  
• When deciding if the Thule Force XT XXL Rooftop Cargo Box - 22 cu ft # TH6359B fits the factory roof rack on your 2018 Tesla Model 3, there are a couple things to consider. First off, I recommend measuring the width and height of your crossbars. Since the # TH6359B is compatible with crossbars that do not exceed 3-5/16 inches wide x 1-1/2 inches tall, it is important to confirm that your crossbars fit within these parameters. This requirement is the same for the Thule Force...

• Can I Use Inno Wedge 660 Rooftop Cargo Box On Tesla Model 3 Factory Roof Rack Bars
  
• The low profile design of the Inno Wedge 660 Rooftop Cargo Box - 11 cu ft - Gloss Black part # INBRM660BK is great from an aerodynamic perspective. It helps to minimize drag and wind noise because of it's shape. To determine if the box will fit your Tesla roof rack and roof it will take some measuring. The memory mount clamps included with this box fit a maximum cross bar size of 3-1/2 inches wide and 1-3/8 inches tall. As long as your bars do not exceed these measurements or...

• Yakima Rooftop Cargo Box for Tesla Model 3 with OEM Aero Roof Rack
  
• The Tesla OEM roof rack for the Model 3 uses elliptical type crossbars, often also called "aero" bars for their aerodynamic shape. On an electric vehicle the rack's aerodynamic drag does become more of a concern than it would be on an internal combustion vehicle. I could not find dimensions for these crossbars but all you need to do to confirm compatibility with any given cargo box is to measure the bar dimensions, width and thickness, and to also check the center-to-center...

• 2018 Tesla Model 3 OEM Roof Rack Compatibility with Thule Rooftop Cargo Box
  
• I looked up your 2018 Tesla Model 3 OEM roof rack and they don't give any dimensions. Based on the aftermarket options for your vehicle, I can assume your crossbar spread and it will be within the requirements of the 23-5/8 to 36-7/8 inch on center requirement of the Thule Motion XT # TH629806. The OEM roof rack is rated for 150 lbs total and this carrier weighs 46 lbs so you will be able to carry 104 lbs of cargo maximum to stay within the capacity of your vehicle and roof rack....
