Our roof racks were designed with several factors in mind – design, functionality, durability, longevity, and desirability.  There was a tremendous amount of R&D that went into the mounting brackets as the load distribution is very important as is not damaging your truck when there is a load on the rack.  Additionally, every roof is a little different so we designed a bracket that will adjust to compensate for those differences.  The slats are all aluminum and can be switched out in the event of any damage.  You can add tire carrier mounts in any location on the rack.
