Randall R. just brought his 1991 Chevy OBS to a whole new level with our Shocker XL Train Horns. This setup is loud, commanding, and impossible to ignore, perfectly matching the classic rugged vibe of his OBS.
The Shocker XL is a four-bell train horn system that delivers an authentic locomotive-style chord, giving Randall’s truck a deep, powerful tone that cuts through traffic and turns heads wherever he goes. Each blast is a statement, and his OBS makes sure everyone knows he means business on the road.
Mounted on a classic 1991 Ford platform, the Shocker XL horns blend old-school truck styling with modern U.S.-made train horn performance. The separate bell design gives Randall flexibility in placement, so the horns fit the chassis while still projecting maximum sound forward and to the sides.
Nothing beats seeing customers turn their trucks into legends, and Randall’s OBS is a perfect example. His 1991 Chevy now has the sound to match its attitude, proving that Shocker XL horns are right at home on classic builds.
