Could you explain the advantage of the swedged tubes?

Obviously, the larger diameter produces greater cross sectional strength in the center, but doesn't the narrowed diameter create a stress point?

Doesn't the mechanical swedgeing process work harden the material, which would further weaken the material at the diametrical transition?

Good questions. I’ve honestly never thought about that or researched it. I just know I’ve seen a lot of them used in various classes of stock car racing.
