Here's a quick and easy way to purchase a Thule Rapid Podium Acomplete roof rack for a vehicle with factory flush side rails. Flush side rails differ from raised side rails in that there is a gap between the under side of the rail and the roof with raised rails. Flush side rails typically have a inner ledge that allows secure attachment of a custom engineered Thule Podium Fit Kit which is the interface between the flush side rails and the Thule Rapid Podium Feet and load bars. To order just enter in the required fields; your vehicle's year, make, model, type (e.g. SUV, sedan, wagon) and number of doors. We'll verify the fit in our dealer fit guide and ship the correct foot pack, fit kit, and load bars for the vehicle.
