Aaron I. just took his 1999 GMC Sierra to a whole new level of LOUD with our legendary Conductor’s Special 228H Train Horn Kit!

This classic beast of a truck now commands the streets (and parking lots) with the unmistakable roar of the Shocker XL train horns powered by a 2-gallon air system and a VIAIR compressor. Every honk is pure sonic thunder!

“Didn’t think my Sierra could get any cooler—then I hit the horn. Absolute game changer!” – Aaron I.

Whether he’s pulling into a meet or letting traffic know he’s rolling through, Aaron’s setup demands attention with a crisp, earth-shaking blast. That 228H combo is no joke — LOUD, reliable, and built for real truck lovers. 

If you’re thinking about installing train horns on your ride, let this be your sign. Aaron’s setup proves that old-school trucks + HornBlasters = PERFECTION!

Huge thanks to Aaron for repping the HornBlasters family the loud way!
