More About Performance Diesel Inc.

After working on their own customer’s big rig trucks for many years, PDI realized that simply replacing broken low quality parts with other similarly cheap parts was not the answer. PDI created the Big Boss lineup of performance parts and took the heavy duty diesel industry by storm.

Before PDI begins development on any new product they ask how the it will increase reliability, horsepower, torque and improve fuel efficiency. They offer longer manufacturer warranties than their competitors on their exhaust manifolds, intake manifolds and turbos.
