The Signature Series line is a unique, high performance group of products geared toward the serious competitor, assembled exclusively by Big Power Diesel. In some cases we have been directly involved with the development of these products, while others are simply the result of a close working relationship with these companies. Our extensive experience with these products enables us to offer our customers reliable, expert knowledge and competitive pricing and, as with all products purchased from Big Power Diesel, continuous customer support. The Signature Series will be an ever evolving line of products that will continue to expand as Big Power Diesel continues its relationship with these companies and adds others to this elite list.

We specialize in expert knowledge and installation of performance camshafts, Injection pumps, injectors, fire ringed cylinder heads and more for the Cummins Turbo Diesel.  We can perform anything from stock overhauls to complete, custom builds.
