Generic GM Spring Rate Question

Greetings all,

Calling on the engineers here or those familiar with internal GM spring rate terminology. While not a gmt360, information does not exist on the gmt31xx related forms and I figure the knowledge you all hold over here may help.

Below is a chart with different spring ratings and associated PN's for said springs. I understand the spring rating component but am curious as to what the "check LOAD" category may be. It must be significant in a sense to warrant multiple PN's across a common spring rating, but I am not sure what it references. Possibly the length of the spring? Is it a common terminology that is used in spring engineering that my google skills have failed to pick up?

Thank you and cheers,
