Now you can haul a ton of gear without sacrificing the security of your covered bed. This kit adapts Yakima’s OverHaul HD™ and OutPost HD™ truck rack systems to work with the integrated tracks on Retrax XR Series, RetraxPro EZ-OFF FRC-4000, Embark LS and Pace-Edwards UltraGroove (except for 2004+ F-150) tonneau covers. So you can enjoy the advantages of both a retractable tonneau cover and an overbed truck rack.
