Kleinn Onboard Air System & Model 730 Demon Triple Train Horn Kit for Ram (2021-24) 1500 TRX

Built specifically for the TRX, this Kleinn onboard air system and Model 730 Demon train horn kit fits 2021-24 Ram 1500 TRX trucks: 4x4, Crew Cab, 5'7" bed, 6.2L supercharged V8, all trims. The brackets are chassis-specific and bolt to factory mounting points under the truck.

The 6450RC compressor is waterproof and rated for 100% duty cycle. Kleinn's TRX guide calls it a 150 PSI kit, with a 2151 pressure switch (110 PSI on, 145 PSI off) and a 175 PSI pop-off valve. Air is stored in an inner-coated anti-corrosion steel tank and sent through a 1/2" Max-Flow line to the Model 730 Demon horn. The rest of the box: INF-1 tire inflation kit with a 24' quick-connect hose and glow-in-the-dark gauge, a coupler relocation kit with 12' of airline, a canvas bag, relay, wiring, loom, horn button, fittings, thread sealant and hardware.

TRX owners air down. Having a compressor bolted to the frame means no hunting for a gas station air pump after a day in the sand, and the spare tire stays right where it is. The 730 is loud enough to get noticed on a crowded trail or a busy interstate.

Not compatible with Mopar Power Steps; compatible with the AMP Research PowerStep Series. Kleinn recommends not running the system above 150 PSI. See the Kleinn install guide for bracket placement and wiring.

For a bigger blast later, the Ultra BlastMaster valve upgrade kit is built for 730 systems. Covered by a 1-year limited warranty, and Kleinn lists extended 2-year coverage on the compressor and horn.
