Hello Tien, thanks for reaching out. I went and grabbed one of the RockyMounts Hitch Extenders # RKY10011 from our warehouse and I measured the hitch pin. With the key inserted it is about 6-1/4" long. The key itself is about 1-7/8" long. Without the key inserted, the lock it about 5-1/5" long.

I hope this helps. Are you using this for a bike rack? What kind?

Hey Tien, did those measurements for the RockyMounts hitch extender give you enough clearance on your Tesla? Your feedback could really help others working with tight space around their hitch locks.
