Mopar says my 2012 3500HD 6.7 4x4 came equipped with HD suspension consisting of springs and shocks. Online I’ve found two spring packs, a std. 2800 lb. pack with 3/1/3 and a H.D. 3,300 lb. pack with 4/1/1. My Ram clearly has the leaf spring pack with 3/1/3. I really wonder if I got the HD suspension. Where can I find the mopar part numbers online to decode the suspension part numbers installed on my Ram. My truck has a permanently mounted 3,800 lb. RV coach Tiger Models - Tiger Adventure Vehicles and the suspension is overloaded. So as it is, I need to upgrade from factory installed and am thinking if I had the HD I might be alright.
