The angles don't get that bad as long as your under 3 inches. What you want to do to find out what kit you want is park on a flat surface and measure the height from the top of the wheel well to the ground on the front and back. The difference in those measurements is the size of the level you want.

I recommend it as it is one of the best value/appearance upgrades you can do to your truck. It will feel like a new truck when you do it.

 

go 2.5 and youll be fine.. ive had mine on for a while with no problems.. im about to get my truck lifted 8 inches but it made a big difference when i put the level on it.. you wont regret it.. just keep it under 3 inch unless you use a rear block

 

thanks guys alot im gunna go with the hb 2.5 aluminum leveling kit hopefully next pay check!!
