Question:
I see that user Glenn had trouble with this adapter for his 2024 Tesla Model Y factory rack too small. Do you have a Mighty Mount adapter suggestion for that rack 39H?. I also have a Model Y factory rack 2024. Yakima is no help: talk to Tesla. Tesla doesn’t know anything about third party systems attachment to their factory rack. I have Hull Raiser kayak racks and the default fitting that comes with it is terrible. Thx.

Hey Dean. I do not have any information on factory roof racks. OEM's don't put that out there. What are the dimensions of your 2024 Tesla Model Y's factory crossbars?
The Mighty Mount 39H Accessory Adapter for Yakima CoreBar and JetStream Crossbars item # Y03539 fits crossbars that measure 1" tall by 2-3/4" wide.
You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.

The Tesla Model Y bars are 3 1/4”+/- wide, so the 39H Mighty Mount would be a non starter at 2 3/4”. Thx.
