Currently N2itive makes parts for the Tesla Model S and X.  All of our parts will fit both of these models interchangeably from 2012 to 2020.  We are currently designing new parts for the 2021 models with their new suspension system including the Plaid version.  Our lowering links for the 2021 standard and Plaid versions are now available.
Please note, the RSX-1 lowering links will only work on the S or X with air suspension. All Tesla Model X's have air suspension. Most Tesla Model S's have air suspension. How you can tell is if you can adjust your ride height on your screen such as "Low", "Standard" and "High" then you have air suspension. Any questions please let us know!
We are currently in the process of designing suspension parts for the Tesla Model 3 and Y as well.
