3 reviews for Kleinn 09-18 Dodge Ram 1500 Onboard Air System w/ Model 730 Horns

  1. Charles Harris

    Love having onboard air on my Ram. airing back up after trails is effortless. The 730 horns are a great bonus and the system is very reliable.

  2. Scott Rathjens

    Got the Kleinn system for my Ram 1500 primarily for trail use, being able to air up after a wheeling run is incredibly convenient. The 730 horns were a bonus but they’ve become a favorite feature. The compressor fills fast and the tank holds pressure well. Mounted everything neatly under the hood with room to spare. After a year of use and several trail runs, not a single issue. Kleinn’s build quality is obvious. These are not cheap Chinese compressors. Highly recommended.

  3. Ambrose Gaskins

    Put this Kleinn air system in my ’15 Ram for filling truck tires and running air tools at the job site, and it’s been a great addition. The 730 horns are aggressively loud, exactly what I wanted for safety on busy job sites. Compressor cycles quickly and doesn’t strain even at higher pressures. Mounting brackets included made for a clean, out-of-the-way install under the bed rail. Wiring harness was well labeled which made hookup painless. Solid dual-purpose unit that’s earned its keep on my work truck.
