Excuse me, but air bags INCREASE load capacity? How? Do they magically take weight off the axles, tires? Do they make brakes more efficient? I'm stumped.
What is used to determine load capacity? Load capacity is a combination of factors, correct? I have already stated my tires are rated at over 3000lbs each. The brakes are rated to stop weights much more than what I am stating based on Toyota's figures. So what is the limitation? the springs... So, tires that can handle the weight I am putting back there, brakes that can handle the weight, but springs that cant... increase the amount that the springs can handle.... therefore increasing the capacity of the load.
If you have a chain, and it has a link that can handle 1500lbs, one that can handle 3000, and one that can handle 10k, then the "weak link" makes the overall strength of the chain at 1500lbs. If you increase the strength of that link to be able to handle 5000lbs, then the weak link then becomes the 3000lbs link. So, by increasing the ability of the weak ling, the overall capacity that the chain can handle is increased.
Are you under the impression that because the springs cant handle the weight, that by putting in something to assist the springs, or replacing them with something better doesnt increase the ability of the truck?
