the Adrenaline kit I got was actually a rough country level kit.. it was the 2.5" though.. now that I have a lift and still have those keys- the torsion bars are set much lower than they were..

I did the easy ride leaves in the ****.. they 'sposedly increase payload and give me 3" ride too.. I dig 'em.

 

I did new keys for the front of mine. I also put some 2000# airbags in. Unless I run the bags close to max pressure, I don't notice them much at all. Just make sure to upgrade your shocks and get an alignment.

 

I tried cranking the stock keys and that didnt really work for me, so I broke down and bought the leveling kit for my truck.

From what I know, the new keys are suppose to make it so you can gain 2" on the front without having to adjust your adjusting bolts as much. This was not the case in mine. As I stated before, I put the new keys on and had to really crank those adjustment bolts all the way in. Doing this, I still only got 1 3/4" lift out of them. According to the kit directions, Im suppose to get 1"-3".
Its about 1/4" lower than the rear which is what I want, but what is the deal with the bolts??

 

The ONLY time I have ever seen cranking the stock keys not work to level the truck is because the guys torsion bars were bent. Which would also explain why you had to crank the bolts with level keys...
