I thought the load was more compression, especially for drag situations?



Its more of a sheer load on the front hanger, although it may be slightly compressive for the top two hanger studs and slightly expansive on the bottom two studs.

If you look at housing rotation on a launch, this pulls the front spring segment up, which pulls the spring eye up, which pulls the mounting bracket up, and because the mopar hanger is not symetrical, it pulls on the bottom studs and pushes on the top studs.

If you use a Cal-trac type device, it resists compressive loading, but this is due to the housing rotation around the axle that would compress anything mounted under the axle centerline.

The reinforcing plates are not a bad addition if you want them.
