Question:
What is the weight capacity of the rack? Can it accommodate a Thule car topper? I have a 2025 Tundra TRD Pro with the integrated rail systems.

Hi David; the Front Runner Truck Bed Rack # FR36TJ has a capacity of 55 lbs per bar with the weight distributed evenly. Most of the Thule roof boxes like # TH614 (I'm assuming this is what you meant by car topper) max out at a crossbar width of 3-5/16" and these are 3-1/2" wide so you won't be able to clamp it on there.
Is roof box compatibility your main concern? If that is the case, you're better off with a rack like the Adarac M-Series # A65AG or the Yakima BedRock HD # Y01160-58. Both have a higher capacity and would be compatible with the Thule cargo box.
