if i run 6" suspension lift and 2.5" leveling kit and the suspension kit comes with a 3 inch block for the rear, will that sit level? i dont think it will and i can NOT stand the look of the rear sagging. if anything it would be aight to have it a half inch higher or just plain level. What would be my options of lifting the rear up level or just a bit higher. NO SAGGIN! thanks guys!

Just go with a taller lift block or an add-a-leaf.

 

how many inches in the back do you think would be needed?

 

I had the same setup. To get it to sit level. Get the 5 inch block and then the 1.5 Add A leaf.
