The HornBlasters Conductor's Special 127H Train Horn Kit is a popular choice for anyone that doesn’t have a lot of room to work with. The Shocker horns and 127H Onboard Air System make the perfect pair when space is scarce. Most train horns come on a huge metal manifold, which looks really cool but can be difficult to fit if you are limited on install space. The Shocker horns, however, are four separate bells made of super durable ABS composite. This means the horns don’t have to be installed in the same spot and can be spread out in just about any configuration. Don’t let them fool you though; these horns have the full range and volume of the real train horns. This kit is not only loud, but is also hand-tuned to the exact US Train chord specifications. While the 127H system is not enclosed and will need to be installed in the upright position and out of the elements, it does have one of the smallest footprints out of all the onboard air kits that are available. Sporting a 1.5 gallon tank and Viair 275C, the 127H provides you with enough air for a 3 second blast time and recharges from 90-120 PSI in only 30 seconds. This is a self-contained kit, meaning installation is easy and the only maintenance needed is draining the tank on a regular basis. If you are looking for a big train horn sound in a small package that doesn’t require a lot of upkeep, this is the kit for you. This kit does not fit the Spare Tire Delete Bracket. This kit includes: Shocker S4 Train Horns, HornBlasters 1.5 gallon air supply unit, HornBlasters 90/120 PSI pressure switch, 10 ft. of 5/16” DOT approved airline, 17 ft. of ½” DOT approved airline, 17 ft. of 10 gauge & 18 gauge power wire, ½” NPT electric solenoid valve, brass NPT fittings kit including safety valve and blowoff, wiring and plumbing kit, mounting hardware, detailed instructions, and earplugs.
