DIRECT FIT TRAIN HORN AND ONBOARD AIR SYSTEMS FOR 2011-2016 FORD F-250 / F350 SUPER DUTY
Overview
Power & Performance — Heavy-Duty Onboard Air Systems
At the heart of every Kleinn onboard air system is a 100% duty-cycle, submersible waterproof air compressor engineered for extreme reliability, fast recovery, and maximum airflow. The high-output compressor feeds a high-capacity, anti-corrosion inner-coated steel air tank built to withstand harsh under-vehicle conditions while delivering consistent pressure and long-term durability for your rig.
When activated, Kleinn train horn systems deliver a true locomotive-style blast engineered for maximum airflow and aggressive output. Whether equipped with ABS (230) or stainless steel (730) horns, each system is tuned to produce a serious road-clearing presence and the kind of attention-commanding performance professional truck builds demand.
