The Shocker XL is a four-bell train horn system that delivers an authentic locomotive-style chord, giving Kevin's F-250 a deep, powerful tone that cuts through traffic and turns heads wherever he goes. The installation on the 2021 F-250 was completed with careful routing of air lines and secure mounting to minimize vibration.
