I havea 2wheel drive, 05 QC Dakota, with the 4.7. I haul a lot of cars behind my Dakota and have found that i think it'd benefit from a little more suspension in the back. Does anyone know of anyone offering like an add-a leaf for the rear springs, or any other beefier setups available?

 

I was also looking for an add a leaf or maybe even an airbag setup so it dont sag when I pull the trucks or racecar around
