VS30 Sprinters (2019 or later chassis) with nothing under the passenger seat base.
Will NOT fit chassis-cab sprinters with a low seat base as they have an extra brace under the passenger seat base. It MAY fit a chassis-cab with a high seat base (non swivel).
Aftermarket swivels WILL NOT work at the moment without some modifications/spacers. We are working on native fitment with various swivels.
