I am about to put in a new set of leaf springs and rancho shocks. Any bushings or the like that I should replace or upgrade while their in there? Gotta 99 5.2.

 

Id suggest getting a full suspension poly urethane bushing kit from the manufacture you bought the suspension from to replace the old factory rubber ones with.
This will help the ride and control of your vehicle

 

Are there any in between bushings. I mean hardness wise is there only OEM then straight to poly? Different grades of poly? I heard there were some hardness differences on bushings for other vehicles. I am getting leaf springs off of a 2003 Durango so they should be in fairly good shape. Are there bushings on the leafs that I should replace? I also wasnt sure if there wasnt anything else to replace
while the back end is fairly exposed. I am going to get some front disc and rear drum work done also.
