What you have there are the 'factory overload springs'
Is the SPID still present in your glovebox? ....if so, post a pic up and that option should be listed there.
Also, check your GVW plate in your door. If your truck is a 'heavy 1/2' ton (for that year) then your plate should saw 5400lbs maximum instead of the typical 5000 lbs.
Normally the heavy 1/2 tons have the heavy rear spring, heavy front springs and heavier tires on them.

All Good
