It holds the torsion bar ends and resists their torque with a 3-ft. long I-beam section. The amount of deflection of that cross member is minuscule relative to the body. The billet piece just makes it more minuscule.

I was looking at it more from the standpoint of the strength of the crossmember not really looking to “stiffen the chassis.” I have seen guys get cracks in the factory aluminum crossmember so I think this might be a better option to avoid that.
Thoughts?
