It's just a spacer kit. I'm sure you could find a cheaper one if you just go this route. Hard to mess up manufacturing spacers.
If you are just trying to get looks out of it this kit would be fine, if you want to trail ride or something more you might want to look into a 2.5" suspension lift and maybe a 1.25" body lift.
We just installed a 2.5" and he's running 33's on it and didn't break the bank.
