They just need to add it to the product heading.
In the detailed product description it states "Fit: The 27 Piece Agile Offroad Lug Nut Set Fits Factory Alloy & Factory Steel Grenadier & Sprinter wheels plus Agile Offroad Aftermarket Wheels."
I presume the seating profile of the alloy and steel wheels is identical.
We can make some corrections with the description to make it better.
However, the Sprinter shares the same kit, and MBZ uses a Ball Seat with factory wheels.
