stock suspension

the shocks are worn out on my dd at 90,000 miles. my question is what are the best most long lasting replacements. also could I put the citadel shocks or rear load leveling shocks from the trailer tow package on my r/t for a softer ride or for better trailer control with the load leveling shocks?

Hello, My Durango is sitting on stock suspension and also is using the stock rims. It needs some new tires soon, and I am currently looking at some BFG All Terrain KO2s. Anyone know a good size for light offroading and road driving?
