About us

"Our complimentary backgrounds and personalities have created a synergy that ultimately it makes us the successful business we are."

Established in 2005 American Turbocharger Technologies, LLC was born out of a working relationship with a team of subject matter experts in every phase of the Turbocharger industry. Principal Bob Kappesser and his team have well over 200 years of combined experience in the turbocharger and diesel engine repair industry.

We specialize in Alco, Elliott, EMD and G.E. diesel engine turbochargers and technical support for all Alco model diesel engines.
