depends how much you wanna spend. ready lift makes a 2.5" up front and 2" rear that sells for $700. and you can clear 37" tires. if you wanna go to a nice 4.5" i would recommend the icon lift hands down.
IMHO moto metals are nice, XD's are better.
im going with XD's on mine just like many other people on here and you wont be disappointed.
