Not sure how much power you are making 98Ram but I advise against removing leafs method.

Maybe scratchn has a strong spring pack with only 4 but I took the second leaf out of my 87 D100. It was a reg cab short box. 5.9 Magnum with a stick.
It created many problems. There was the biggest problem of wheelhop. I was also scared of losing the rear universal joint because the weak springs were now allowing axle housing rotating.
You say you are not hauling but I was truly ashamed of my truck sagging when we tried to load furniture in it and she was bottomed out. Solution unloaded it and jamming it into my 94 LHS which was happy with the payload.
After all that crap, it only lowered it like less than an inch.

The hard facts are lowering should NOT be done by lowering the spring rate.
Relocate the springs or have the same set de arched by a truck shop.
