ARB Front end sag

Anyone have any advice on how much a ARB will make my front end sag? . I am running 285's via a spacer lift and the TSB in the rear. (I know I am saving for Icon's at the moment) I got a deal on the bumper I couldn't pass up. Pics are in my profile. I just don't want to have a front rake

 

need sprung in the fronty

 

my custom bumper with winch all decked out weighted about 200 pounds i have had the stock springs on there with a spacer lift and 285's with wheel spacers and no rub at all. it dropped my front end about 3/4 to 1 inch. i have a lot lot of weight on my truck. hope that helped.

 

When I installed my ARB with stock springs the front dropped 1/2" this is with no winch installed. I now have 886 springs with a warn winch.

 

Mine only dropped 1 inch. But thats with a winch and on stock suspension
