Well guys, You may not have ever seen overload springs on a 1/2 ton, but there is always a first! These came on my truck which only had 2 previous owners. The owner before me did the paint and body work and the owner before him was a farmer from Topeka, Kansas. The guy I bought the truck from said everything on the truck came on it as is when he purchased it. Now, does anyone know where I can find these overload spring bumpers, or the rubber inserts for these bumpers?
