The only time the relationship of your spring pack changes is when you hit a bump and the axle moves up momentarily.

The difference in yours & jasin's is yours has the top 2 very stiff overload leafs that don't come into effect til loaded heavy & if only loaded not quite totally down on the overloads will jar your eye teeth at every little bump.
Jasin's has air bags instead of the overloads which I assume are deployed with rearend truck sag with or without a heavy loads as needed to maintain level making the ride less harsh.
