Ahh... closer to understanding, youve somehow read into the product description they have something to do with 'load capacity'. No where is that suggested. Its clearly load CONTROL, emphasized several times.
So indeed, why compare to a product that has a different purpose? Stableloads are closer to sway bar & shocks in purpose, handling.
The comparison to air bags also is on the sway control aspect of air bags..not the ability to add weight. (though the sway control of air bags is limited and can adversly affect, not there intent but mine do reduce sway by the simple limiting of lean).
Regardless this isnt a win situation-what ever works for you is great- Its the 'passion' thats hard to grasp. Ive done a few after market things and was stoked with results. I might recommend but couldnt imagine being that absolute others need to follow. Different mind set I guess.
Not sure: other folks not coming to the same conclusion as yourself and install the same products you have one could make the assumption they are uniformed or misinformed. Thats a statement:h.
