If I use 987 springs, will it raise my truck height when nothing in bed or on hitch?
No these only come in to play when you have weight in the vehicle, they will eliminate sagging these will not lift the vehicle when loaded or unloaded.

Just what the doctor ordered !
I am a 100% disabled American veteran. I have lost use of my right arm and leg. My wife helped me put these helper springs on with little or no hassle. She is not mechanically inclined and loses her patience quickly. However, the instructions were concise and direct. She and I were able to install the product with little or no hassle. They do exactly what they were intended to do. Thank you !
