on rear of my truck its mono leafed but I use Monroe load leveler shocks like these. im not sure what model I bought them for but ill get the part numbers. I also use them on the front for a 90 f150
the shocks did raise it about an inch but the improved ride was worth it and they are cheap. I bought mine through advance auto for $60 a pair
