I already have my t-bars cranked to sit level. Now i was wondering if there was any way i could get any more out of the front with green keys. I would like to put 2in blocks on the rear and still make the front sit level. Any input thanks.

Do a search, you will find more information than you'll know what to do with.

My point of view,
Depends on your truck. You might be able to gain more out of the green keys but for every turn past 2in you are getting closer to the limit. Your ride qaulity will decrease and your starting to put bad angles on your CV shafts.

How much do you have left on the stock adjustment bolts? You might be able to get everything out of the stock keys. Make sure your not bottoming out on the a-arm bump stop. And make sure the shocks aren't holding the suspension up. I cranked my t-bars and the shocks held the suspension from fully extending.

Good luck!

It is not a great idea to go more than 2" of lift by cranking the t-bars. Not only does the ride get progressively rougher, you may run your camber cams out of adjustemnt and be unable to re-align the front end back to factory specs. The Cognito leveling kit (includes upper a-arms) allows proper alignment, but I am unsure about the quality of ride as you go over 2".

Also, make sure you buy longer shocks. IE, 2" longer shocks for 2" of t-bar crank.
