two thule rack system options for 2008 Chevrolet Tahoe roof rack siderails

[TKGsolutions]

My 2008 Chevrolet Tahoe has the side rails installed on the roof, the bars that run parallel to each other from the front to back of the roof on both sides. I like Thule Racks systems but am confused by what a dealer said, which was that there are 2 Thule roof rack model options available for mounting to the 2008 Chevrolet Tahoe roof rack side rails. How do I know which one I should choose?

Yes Thule Racks does now have two options for your 2008 Chevy Tahoe roof rack side rails. They perform and function the smae way however. The difference is mostly a matter of aesthetics...

The Thule 450 Crossroad complete base rack system attaches directly to your vehicle's factory rack side rails, converting your factory rack side rails into a sturdy base rack system capable of safely transporting all your gear. Includes a set of four Thule 450 Crossroad Feet and a pair of load bars. The 58" load bars are the recommended length for your vehicle. You can then attach the various Thule roof mount gear carriers to the load bars.

The Thule 450R Rapid CrossRoad complete base rack system works exactly the same way as the regular Thule 450 Crossroad system except that it uses the elliptical Thule Rapid Aero load bars (the RB53 Rapid Aero bars are the length necessary for your 2008 Chevy Tahoe roof top), which are very sleek and aerodynamic offering a more low-profile and modern appearance. All Thule roof mount gear carriers also connect to the Rapid Aero load bars, either directly or in combination with Thule Xadapt adapters.
