Most Thule products that mount to the Aeroblade using the T-bolt track on the top of the bar are also compatible with the T-track on the WingBar Evo.
The Aero Load Stops (502) and track mounted XAdapt kits are not compatible with the WingBar Evo, because of the thicker bar. These will only fit Aeroblade top tracks.

If you believe your SnowPack or Hullavator requires these parts, contact customer service by phone at 1-800-238-2388 Monday through Friday 8:30 to 5:30 EST.
The part numbers for each system are as follows:
