does anyone know where to find a supercarger kit for a 03 2500 with the v-10

 

I haven't seen any advertised supercharger kits for the Magnum V10, but you could try one used in the Ram SRT10s seeing as the engine layout is somewhat similar.

But a 3rd Gen HD ram with the Magnum V10 is very rare. It's nice to see some of them pop up from time to time.

 

The iron V-10 is very similiar to a V-8 magnum, that kit might actually work.
