These B7 Idler Shafts are made out of magnesium and then hollowed out to lose the most weight possible. They come in at 0.33g/ea whereas the kit aluminum shafts are 0.88g/ea.

Information

• These are raw and will create a thin oxidation layer when taken out of the bag if they don’t already have one, making it look slightly like Damascus steel. The oxidation layer does not change the performance of the product and it is a natural way for the metal to protect itself.
