Your point is well taken. Contrary to what most, I believe feel, I am unconvinced ANY of the aftermarket UCA's offer improved rigidity over the OEM UCA, welds or not. Their main attributes are the better caster mentioned, and extra clearance for coil over options, IMO. And the cost of stamping an improved OEM UCA likely is not cost justifiable for our market just to gain caster.

Besides, om the quality UCA's, no welds have been reported to be failing in normal use.

I also am a believer one can improve typical aftermarket CA's for rigidity, case in point, Pic #7:

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
