i have a 2004 4x4.... i see there are many options but i would like to know what is the better on of them all?

 

The 2" Daystar seems to be a popular leveling kit for the 2004+ trucks.

 

Leveling kits are fine, but the best way would be a replacement coilover shock (like Bilstein or Rancho) featuring adjustable spring preload. They do the same thing as the leveling kits but you gain a much better shock.
