Bully Dog

Bully Dog was formed in 1998 in Aberdeen, Idaho. The founders of Bully Dog – Michael, Phillip, and Daryl Klassen --were heavily influenced by their father Harold's interest in improving vehicle performance. Several years prior to the company's inception, Harold had experimented with increasing performance on his diesel farm tractor by injecting propane into the engine's combustion chamber. In 1998, Bully Dog's owners took this concept and developed and patented a safe and effective propane injection system to enhance diesel engine performance. 

Bully Dog products are developed with you in mind and each of you has a different need, want and desire. Our products, all the way back to the first propane kits, reflect that. Bully Dog products are built to be flexible, allowing each user to get their own desired result, from outrageous performance on the race track to improved fuel economy driving down the highway.

Bully Dog Technologies, LLC is a team built on integrity that is dedicated to leading the vehicle performance industry with an uncompromising code of ethics demonstrated in the soundness of its employees, excellent customer service and superior products.
