The Thule SnowPack L system (model 7326B) is not directly compatible with the standard roof bars of the Dacia Sandero Stepway. The roof bars on the Dacia Sandero Stepway are modular roof bars specific to this car model and do not match the types of roof bars supported by the Thule SnowPack L, which include the Thule WingBar Evo, WingBar Edge, SquareBar Evo, ProBar Evo, Xsporter Pro, and TracRac - Truck/Van.

To find a compatible system, it is recommended that you visit the Thule website to determine the appropriate roof bar solutions for your vehicle.
