max is 2" you could prolly go 2.25 or 2.5 but you really dont wanna go past 2" because then things start to wear fast. and since you have a 2009 try to go to a junk yard a get some 01-07 torsion keys and 01-07 rear blocks. mainly because 01-07 trucks stock were taller than the newer ones so if you get there keys and block and crank em 2" then youll be higher than if you cranked yours 2"

hope that makes sense and if not use the search tool on here and type in pre key mod or somethin along those lines
