I know the H series is not that much heavier but OMG its like driving a tank.

Best spring strut combo set up to handle it to at least be able to do a highway pull without being ALLOVER the road. That is with i think skunk 2 springs and stock struts. They might be ebay springs.......

 

pretty much anything would be better than that, if they're really ebay springs on stock shocks. koni/gc, progress for affordability, PIC Apex's for quality and affordability. make your pick.
