I believe the concept we are discussing is that if we spec this part in a chromoly alloy we can achieve a "STRONGER" support for the same "WEIGHT" as stock. This is achieved with a thicker inner wall from an alloy that is physically lighter then the stock offering. IE same physical weight stronger overall product because it's physically thicker metal in the same outer diameter.

Rob, this is simply not true. 4130 chromoly is virtually identical in weight to mild steel. The misconception that chromoly is lighter than steel comes from the fact that it is much stronger than steel, which allows you to use a lighter gauge and achieve the same strength.
A length of 1" x .120 wall chromoly weighs virtually the same as a length of 1" x .120 wall mild steel.
If you are using chromoly tube with the same o.d. as the factory mild steel boards, but with a heavier wall thickness and a smaller i.d., it will be heavier.

Thats correct.4130 chromoly is virtually identical in weight to mild steel. The misconception that chromoly is lighter than steel comes from the fact that it is much stronger than steel, which allows you to use a lighter gauge and achieve the same strength.
make them out of the same gauge chromoly as the stocker mild steel junk and get no weight penalty and about a 30% strength increase.....
If I recall correctly when the raw chassis came out one of the "big" features were the "cromo" rails. I could be wrong but I think the stockers ARE chromoly.... So, anything built to replace them pretty much has to be heavier to be stronger. Thats ok though, mine are bent and dented and in need of replacement, and I always like to replace broken stuff with stronger stuff!
