Kenworth » T409
The aerodynamics model T409 was updated in 2011 model year together with other Kenworth models. The bolder grille is now lower, allowing air to flow more freely around a wider, more contoured engine compartment. Completing the picture is more muscular wheel arches and streamlined side fairings. The cab is quieter with enhanced noise and heat shielding and there is a wider landing step for better visibility on exiting the cab. The T409 ADR 80/03 engine options include Cummins ISX with EGR and integrated DPF, and ratings up to 525 peak hp and 2050ftlb torque. The new automatic transmission Eaton Ultrashift Plus is available now.
