Welcome to the Den

Diesel Den Performance, located in Philadelphia, Tennessee and owned/operated by Josh Watson has been building performance diesel trucks for years.

Whether you want an extreme sled puller, the best fuel mileage possible or simply want to smoke it up on the streets, the DIESEL DEN can provide you with the parts and service to get you where you want to go.
