Your 1500 more than likely has a 3:55 to 1 gear ratio. What you need to is install 3/4 ton front and rear springs, change the gearing to 3:91 to 1 and have the Dodge place recalibrate your computer to the 391's so your speedometer and odometer will be right.
The springs are a bolt in swap so to have the work done will run around a grand parts and labor. A real cheap way to go and best is to buy the springs from a salvage yard ebay is full of them. That would cut cost in half. The suspicions didn't change from 1994 to 2008.
