I don't know if sagging is the correct term. But the front end is lower then the rear. I have a BDS lift on the truck that was installed by a previous owner. Guess what I need to know is was the BDS kit designed to lift and level the truck or no? I don't want to just go and crank the t bars up and then start eating suspension parts. Also with the BDS lift were new keys included or used factory? Thanks Chris

 

Usually with full size trucks you have to do a levelling kit after a lift.
