DIRECT FIT TRAIN HORN AND ONBOARD AIR SYSTEMS FOR 2009-2018 RAM 1500

$1,599.95

Overview

Power & Performance

At the heart of every Kleinn onboard air system is a 100% duty-cycle waterproof air compressor engineered for extreme reliability, fast recovery, and maximum airflow. This high-output compressor feeds a high-capacity, anti-corrosion inner-coated steel air tank built to withstand under-vehicle conditions while delivering consistent pressure and long-term durability.

When activated, Kleinn train horn systems deliver a true locomotive-style blast engineered for maximum airflow and aggressive output. Whether equipped with ABS or stainless steel trumpets, each system is tuned to produce serious road-clearing presence and the kind of attention-commanding performance truck owners expect.

These systems don’t just outperform typical aftermarket horns — they bury them. Massive airflow, consistent pressure, and true onboard air capability make this one of the most powerful direct-fit train horn and air systems available.

In addition to horn performance, the onboard air station provides real-world utility with tire inflation capability (capacity varies by model) and accessory support.

True Direct-Fit Installation — Engineered in Tucson, AZ

Every Kleinn direct-fit train horn system starts at the Kleinn Automotive Accessories engineering facility in Tucson, Arizona, where the team designs and builds precision-fit, powder-coated steel brackets that make these kits truly direct-fit.

These brackets bolt directly to factory mounting points, delivering a flawless OEM-style installation without guesswork or flimsy universal hardware.

• 100% bolt-on design
• No drilling
• No cutting
• No welding
• No fabrication required
• Clean, under-truck mounting
• Spare tire retained

The result is a professional installation that looks factory but performs far beyond stock equipment.

Built for Long-Term Performance

Kleinn systems are engineered for long-term reliability, heavy-duty performance, and minimal maintenance. Every component is built to withstand harsh under-vehicle conditions while maintaining consistent air pressure and dependable output.

Each complete system includes the Kleinn INF-1 Tire Inflation Kit, providing practical onboard air capability for real-world use.

Included in Complete Systems:

• Heavy-duty tire inflation air hose
• Quick-connect fittings
• Glow-in-the-dark tire inflation gauge with integrated pressure release
• Complete wiring harness
• Fittings, airlines, horn button, and mounting hardware
• Kleinn Juice-1 thread sealant

Whether you’re blasting the horn, airing up tires, or powering accessories, this system is built to stay strong and stay loud — backed by an extended 2-year warranty on included compressors and horn assemblies.

Upgrade Options & Model Comparison

Ultra BlastMaster™ Upgrade Kits

For drivers who want even more output, the Ultra BlastMaster™ Upgrade Kits increase horn volume by approximately 30–40% by delivering dedicated high-flow air to each horn driver.

Depending on system configuration, upgrade kits include:

• Heavy-duty VX6003 brass solenoids
• Dedicated high-flow airlines
• Manifold and required fittings
• Tank compression fittings

More airflow. Faster response. Maximum output.


Kleinn 230 vs. 734 Bolt-On Systems — What’s the Difference?

Some direct-fit bolt-on train horn kits are available in two performance levels: the Kleinn 230 Series and the Kleinn 734 Series.

230 Series — High-Performance Entry Level

• ABS Black Plastic Trumpets
• 1/4" high-pressure airline
• 6350RC 150 PSI Waterproof 100% Duty-Cycle Compressor
• Tire inflation capability up to 33"

Ideal for drivers who want powerful, reliable performance without stepping into the top tier.

734 Series — Maximum Airflow. Maximum Output. Maximum Attitude.

• Stainless Steel Trumpets
• 1/2" high-flow airline
• 6450RC Waterproof High-Output 100% Duty-Cycle Compressor
• Tire inflation capability up to 37"

Designed for drivers who want the loudest output, faster air recovery, and maximum airflow straight out of the box.

If you want loud, the 230 delivers.

If you want the loudest, the 734 is king.
