just bought 04'ram quad cab
I can't remember which link it was but I saw a truck with a 4" spinsle lift and 3" spring lift and a 3" block in the rear to level it and he slaped on some 35" tires. Is that what you are looking at with the 4" lift?
there are many options available as far as a lift goes.
my personal preference is the superlift systems: www.superlift.com
I was thinking of the 6" lift and 37" tires or the 4" and 35"
Others include

Just a matter of looking at the available lifts and deciding which one you like and will work best for what you will be doing with your truck. Each company makes thiers slightly different
