It's not that easy. There are (7) different front spring choices for an '03, the lightest being spring code "R" at 3600 lbs and the heaviest being "X" at 6000 lbs. You'll find the spring code on the sticker on the driver's doorjamb.

Take a look at the sticker in the door jamb of the drivers door. Toward the bottom right of the sticker you will see the letters "spr" below those letters there will be two more letters such as XB the first letter X is the front spring code. In this example XB you would have X code or plow prep package front springs. Other front spring codes are U, V, W, and X in ascending order of spring weight capacity.
Also we need to know what cab the truck has, long or short bed, DRW/SRW, and engine.

I'm 4400/6830 with "T" code springs so it's probably got "U" code fronts which are 4800 lbs.
