| The Thule 430R Rapid Tracker footpack works in conjunction with factory installed roof rack systems that feature tracks. The 430R utilizes the Tracker fit kits that provide the custom fit. The Rapid Tracker foot then snaps quickly and easily into place with no extra tools. The Thule 430R Rapid Tracker footpack looks great when combined with the Rapid Aero load bars and makes a rack that is easily swapped between vehicles with factory installed tracks. As always, the Thule 430R Rapid Tracker foot pack is compatible with Thule’s One Key System of locks. Also be aware that installing most accessories to the Rapid Aero Loadbar requires one of several Xadapter hardware kits. Thule fairings (870XT, 871XT, 872XT, and 873XT) however, have a special bracket included that allows them to fit either the standard square Thule bar or the Thule Rapid Aero load bar. |
