Yes, the recommended Thule AeroBlade Edge Roof Rack for Raised, Factory Side Rails - Aluminum - Black # TH7503B-TH7504B has two different lengths in order to fit your 2021 Mercedes-Benz GLE. The front crossbar dimension is 39-3/4 inches long x 3-1/8 inches wide x 1-1/8 inches tall (with a usable crossbar length of 34-38 inches) and the rear crossbar is 36 inches long x 3-1/8 inches wide x 1-1/8 inches tall (with a usable crossbar length of 30-34 inches). Different crossbar sizes are sometimes necessary for vehicles that have roofs that narrow or have factory rails that narrow inward from front to back. The AeroBlade Edge # TH7503B-TH7504B only fits the wagon version of the 2021 Mercedes-Benz GLE.

If you are looking for a fit that is compatible for the coupe model, you will need the Thule AeroBlade Edge Roof Rack - Fixed Mounting Points/Flush, Factory Side Rails - Aluminum - Black # TH7603B-TH7604B as well as the Fit Kit for Thule Podium-Style Roof Rack Feet - 3152 # THKIT3152.
