Stock, the DRE typically come with 3/4" of thread showing. This is about 2" of lift on a 4wd, about 3" on a 2wd. These numbers are NOT concrete. If your Titan sits low now, then these numbers are easy to get, if it sits tall from the factory, then it will be much harder to get the full amount of increase. If its an '08, you will only gain about 1" of lift on a 4wd, 2" on a 2wd. Dont flip the hat now, get UCA's. Adding the uca requires the addition of a billet spacer (or flipping the hat and cutting, grinding and hammering), you'd have to take the shock out anyway, if you want to flip the hat, do it then. Things to note; there are two bolt patterens, use the one with the dimples. Be sure the lower spacers push the shock away from the axle. If you need to adjust the height, the ratio is about 2:1....1/2" of lift is 1/4" of preload.
