Hey Dion, the EcoHitch part # EH84CR is a fit for your 2021 Polestar 2 and a great option so you are off to a solid start. You will need trailer wiring too to control the taillights of your trailer and for that I would go with the # 119250KIT which does not require any splicing into the vehicle's taillight connectors.
To reduce noise the etrailer anti-rattle part # e38FV would be a really good option as it will hold the ball mount tight to the hitch opening. We don't have any suspension... view full answer...
We do have a hitch for the 2022 Polestar 2. The Stealth Hitches Hidden Rack Receiver # SH85YR is the one we carry out of the two you mentioned. If you plan on using it for towing you will also need the Towing Kit w/ Ball Mount and Trailer Wiring # SH28GR. view full answer...
Yes, we do! I checked with both EcoHitch and Stealth Hitch. The only hitch I was able to find that fits your 2022 Polestar Model 2 is the Stealth Hitches Hidden Rack Receiver item # SH85YR. view full answer...
