Ok Here is the deal, My mother in law pulls a 2 horse trailer with her 02 Dakota 4x4 with the 4.7l V8 and towing package. She has had it for about 3 years and it never use to sag in the rear when she pulled the trailer but now when she hooks the trailer up it Sits alot lower than it use to. What would any of you recommend suspension wise for the rear of the truck? anything? how about a air ride system? Or just new shocks or leaf springs in the rear, Any help would be appreciated. Thanks

 

I think you can get the springs reworked on it and that should put it back at the oringal height when the trailer squats on it. I bieleve it is called "coldworking" the springs.

 

you can get helper leaf springs
