Holden Mann wanted maximum volume for his 2017 Ford F250, so he went straight for the top of the lineup with the Shocker S6 544K Nightmare Edition. This isn't your standard four-bell setup. The Nightmare Edition packs six Shocker train horn bells, including extra #2 and #3 bells that create a richer, fuller chord that's noticeably louder than anything else on the road.
The complete kit came with everything Holden needed: six hand-tuned bells, a 5-gallon 8-port air tank, and the HornBlasters 1NM air compressor. At 150 PSI, this system delivers 8-10 seconds of continuous honk time with rapid recovery between blasts. The components mount cleanly under the truck, keeping the professional appearance of his F250 while adding serious sound authority.
The onboard air system does more than just power the horns. Holden can use it for tire inflation on job sites, run air tools, or add air-powered accessories down the road. The 8-port tank design gives him plenty of options for future expansion, making this upgrade as practical as it is powerful.
