Van & Patty Haisley started HAISLEY MACHINE REPAIR in 1985 after moving back to Indiana from stays in Texas and Germany while Van served 7 years in the military. Our son Curt joined us full time in 2004 and the rest is history.

We started out offering machine shop services and general diesel repair work. The machine work slowed but the search for more horsepower quIckly took over! First with the 6.2 Chevrolet trucks, then the Cummins! In 1994 we decided to specialize in Cummins engine repair and performance and have been very fortunate to continue that today.
