2 different options:
Option 1: Spacers, these push your stock coilovers down and create your lift. These can be found at almost every off road shop.
Option 2: New coilovers, expensive but create a better ride. A few examples are Fox and King. You lift the front of your truck by adjusting the amount of preload. These will need to be ordered or if your lucky your local off road shop may have a set in stock.
I used to have spacers on my 07.5' Sierra and it really tightened up the suspension. Depending on your budget, go for what's best for you. It's the difference between $200-300 for spacers and $2000 for coilovers, it just depends on what you want.
