Features

Overview: The Thule 421-Xsporter medium-duty rack system designed to maximize the load capacity of select pickup trucks. The 421-Xsporter features long lasting, great looking high strength aluminum construction. The Thule medium-duty rack system can accommodate a load capacity of 450 lbs. The length of the cross bar is 71", while the height from the bed rail to the top of the cross bar is 25". You can raise the load bars to carry long loads or lower them for convenient bed level loading. The 421-Xsporter offers versatile aerodynamic load bars to accommodate Thule carriers. This Thule rack system features a locking system which includes four locks and one key. The 421-Xsporter rack system is easy to install with no drilling required.

Note: Excessive rust in truck bed decreases carrying capacity and could result in system failure. Vehicles with bed liners could require modifications.
