The Thule 430 is a great tower system for mounting on a variety of factory installed tracks, camper shell applications, and certain fixed-point installations
The 430R works exclusively with Rapid Aero aluminum load bars and Tracker II Kits to create a multi-sport foundation that works on a variety of applications
The Crossroad Half-Pack can be used with another half pack to create a hybrid rack system where only one crossbar is attached to the elevated siderails
A pair of Yakima Control Towers for that custom rack installation, multiple rack solutions systems, or incase you want to add a third bar to your setup
