1/64 Scale Airhorns – Replacement for DCP Peterbilt 389 & Custom Builds

Upgrade your diecast fleet with these high-quality 1/64 scale airhorns. Whether you are repairing a damaged model or starting a ground-up custom project, these horns offer the realistic detail you need. While we designed these as a direct fit for the DCP Peterbilt 389, their versatile design makes them a favorite for builders across the hobby.

At Rockin H Farm Toys, we know that small details make a big difference. These chrome-finished airhorns provide that sharp, reflective look found on real rigs. We source these parts specifically for serious builders who demand accuracy. If you are working on a 1/64 scale truck restoration, these horns replace factory parts perfectly. They restore the “off-the-lot” shine to your favorite Diecast Promotions models.

Versatile Customization Options

You are not limited to just one truck model. These airhorns are highly adaptable. Each horn features a mounting pin for a secure fit on standard DCP cabs. However, you can easily customize them. Simply snip the mounting pin to create a flat-mount surface. This allows you to glue the horns onto various 1/64 scale brands or even custom-printed resin cabs. This flexibility makes them a staple for any custom truck workbench.

Expert Installation Advice

Achieving a professional finish is easy with the right prep work. When you replace horns on an existing DCP model, check the mounting holes first. Use a small drill bit or a round file to clear out any leftover factory glue. This ensures the new horn sits flush against the roof. A tiny drop of clear adhesive will keep them locked in place for years to come.
