I own a 1994 Ford F-150 ext. cab shortbed F-150. I am wanting to lower the rear of the truck 5" without installing a flip kit, which I should be able to do by using lowered springs and shackles. My question is, does anyone know if someone makes lowered leaf springs for my application, or if maybe I could take a leaf out? And if so, which leaf and about how much of a drop will it give me? Also, will the rear leaf springs of a newer, 1997-2001, F-150 fit on my truck. Thanks for any help.
