I believe they were designed by the GM Engineers to bend or twist a bit in use. Welding them to be more rigid may be detrimental.

The design concept behind GM using an I-beam construction for the trailing arms is that an I-beam has very little torsional resistance. Remember the trailing arms mount to the rear axle which articulates, and it also mounts to the crossmember, which is fixed. Therefore when 1 rear tire is goes up, and the other rear tire goes down that twists the I-beam. The rubber bushings at the crossmember take some of the torsional movement.... unless you are using poly bushings... then almost all the twist goes into the trailing arms.

Adding flat bar to the top and to the bottom will not dramatically change the torsional resistance.

Boxing in the side of the I-beam does dramatically change the torsional resistance.
