Welcome to DaRossi.com!
In early 2005 we found ourselves faced with a need to replace the worn out couplers in our own superchargers for our drag racing cars. Finding there were no quality couplers available we designed and fabricated our own. These proved to be reliable and far superior to the factory original. In 2006 we starting manufacturing and commercially selling this new product. To date we have sold over 10,000 throughout the world. We regularly supply to multiple GM and Ford dealerships worldwide along with many private service stations. To date we have never had one returned for any type of failure.
