Yes, you can use the Thule Hitching Post Pro # TH934XTR and it will do a good job for you. You're likely going to need bike frame adapter bars for the kids' bikes and for any other bikes that have aggressive step through frames; for those you can use the # 64005.
I also recommend getting the Thule Snug Tite Hitch Lock # THSTL2 and the Thule Cable Lock # TH538XT to secure your bikes.
I've linked a review video of these parts for you to check out, as well. view full answer...
Hey Leland; thanks for the question and let's start with the accessory you were mentioning, which is the Crossbar SmarT-Slot Kit 2 for Yakima FatCat Ski and Snowboard Carriers # Y03098. This is what is needed to add the T-bolts to both the Yakima FatCat EVO 4 # Y03095 and EVO 6 # Y03096.
That said, I don't know the exact T-slot dimensions of the Tesla Model Y's crossbars. You'll have to measure the T-slots, and I can tell you the T-bolts of the Yakima kit are 1/4" by 1/4". So you can use... view full answer...
Our lightest hitch mounted cargo carrier is the Flint Hill Goods 22" x 49" Hitch Mounted Aluminum Cargo Carrier item # FHG59ZR. It weighs only 23 lbs and measures 49-1/4" long x 22-1/4" wide x 3-1/4" tall.
We've actually tested it out on a 2022 Tesla Model Y. I went ahead and linked the video we made below so you can see exactly what this cargo carrier will look like on your car. view full answer...
Yes, the Inno T-Slot hardware kit part # INBRP12 that you referenced does work with the Inno Roof Box 320 part # IN94FR. This will allow the cargo box to attach directly to the t-slots on the top of your crossbars. view full answer...
The Tekonsha # TK56FR unfortunately isn't a confirmed fit for your 2023 Tesla Model Y, but the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # TK92VR is confirmed to fit and is the only one at this time. view full answer...
I confirmed with EcoHitch and their Trailer Hitch Receiver # EH39FR was just confirmed to fit your 2024 Tesla Model Y this week. This is great since the receiver opening is accessible through the rear cover plate just like a factory option. view full answer...
The 7-Way to 4-Way/5-Way Trailer Adapter # C35FR has additional resistors built in which is only designed for trailers with LED tail lights. Since you have incandescent tail lights you will need to use the basic 7-way to 5-Way Adapter # A75TB. view full answer...
The 24x48-3/4 Carpod Walled, Folding Cargo Carrier # M2205-2201 requires just a 2" trailer hitch receiver opening in order to mount it. This carrier weighs 74lbs and has a 450lb carrying capacity. If your 2021 Tesla Model Y doesn't already have a 2" trailer hitch then I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver # DT58MR. view full answer...
