I got my radiator hoses through Parts Rack. I believe that they were from Snake Oyl. Seem to be good quality and you know that they are more likely to be made to fit your Viper correctly. However, for all I know, they all come from the same source. There can't be a lot of profit in going into production for a Viper hose if there is already a product on the market.
