Lift

so i have an 07 acccess cab black
and i decided i am going with the 3 inch revtek from les schwab with 33 inch mud terrain tires with 20 inch black ultra goliaths, 20 inch black helo maxxx6 or 20 inch black XD Rockstars. Any tips or suggestions before i buy????
the 3 inch was quoted from les schwab at around 550.00 and i still am MAYBE MAYBE considering an OME lift from the truck store down the street but that 800.00 so i hear its like the same thing so no point in spending the extra 3 hundred???
i know the 33's will cause for some trimming. i really would like to get twenties on my truck but i dont see many with twenties so i can tell if thats to much rim and too little of tire?
thanks for any help

will

 

on the wheels, make sure the backspacing is 4.75 or less. anything greater and you may have rubbing on your uca's. in my opinion i wouldnt go bigger than an 18" with only a 3" lift. 20's look better with a 6" lift (on a 35" tire). not only does it give you a smaller sidewall, but a 33 inch / 20 may be difficult to find in a mud-terrain
