I was looking at doing the same thing to my 94 1500.
And I was looking at kits that had replacement springs. However, my research showed that that may not be the best setup for Dodges. I'm told (and perhaps Big Sarge can chime in here) that there are many many different part numbers for springs on Dodges. Different spring rates depending on the options that you got w/ the truck. Down to A/C even. So this changed my thinking a bit. W/ kits that have replacement springs, they probably won't have a spring w/ the same spring rate that you have stock. Meaning that your ride w/ suck!
I've talked to a few folks and Bid Dick Suspensions is suppose to have a real nice kit. W/ Spacers, not springs. And w/ shocks, you're still around $450 I believe.
Just my $.02.
