Your local dealer should be able to order them for you.You want a 047\048 combo with that plow.The Chrysler OEM springs are the only ones that seem to hold up well,and are consistent in their spring rates.
looking at my springs, the pass side is labeled 39, no label on drivers side, can anyone help me find out what spring is on the drivers side, and is the 47/48 spring combo the common spring upgrade for the 2500's to carry the weight. oh, and the 47 is the pass side right?
You can put the heavier springs in,it will just ride a little stiffer overall.Too much spring never hurts.
Your truck probably has a 046 drivers side spring,most likely part of the AHD plow prep package.Most of the plow prep diesel had the 039\046 combo.The stiffer drivers side spring is to offset the extra weight of the steering box,diff,driver,fuel tank,etc.
The part numbers for the 047/048 combo are: 52039048 and 52039047. The last the numbers are the spings Id. I purchased mine from one of the local dealers on 12/05/03 and paid $202.73 with a Chrysler discount. Whithout would have run me $270.30 accourding to my invoice. The new coils worked out great.

Hope those Numbers help you out...
