Ford L series

The Ford L-series is a range of commercial trucks that were assembled and marketed by Ford between 1970 and 1998. The first dedicated Class 8 conventional truck developed by the company, the L-Series was colloquially named the "Louisville Line", denoting the Kentucky Truck Plant that assembled the trucks. The successor to the Ford N-series and the Ford F-900/1000 Super Duty, the line was a Class 6-8 truck. Slotted above the medium-duty F-Series, the L-Series was produced over a wide variety of applications through its production life, including both straight trucks and semitractors.

The L-Series was produced in Louisville, Kentucky, alongside medium-duty F-Series trucks; at various times, it was also produced alongside the C-Series COE (and the CF-series Cargo that replaced it). For its second generation introduced in 1996, the Ford Louisville nickname became the official name for the model line. Sold primarily as a semitractor, the aerodynamically enhanced Ford Aeromax served as a flagship model for both generations.

After the 1996 sale of the Ford heavy-truck line to Freightliner, the production of the second-generation L-Series was transferred from Ford to Freightliner during 1998. The model line continued under the Sterling Trucks nameplate, lasting through 2009.
