ok this may get moved but i think it is a diesel question , i am thinking of putting new springs in my bj60 i am planning on ome dakars i was going to go with light or med springs but then i started thinking that the 3b might be too heavy for the lighter springs ? also i am still looking at buying another hj60 how much heavier is the 6 cyl diesel do i need heavy springs , i want a compliant ride not a rough one .
