Speaker Brackets – 55-59 GMC Chevy Truck

The brackets are offered in a 6.5" and a 6"x9" opening. The opening dimensions are in the product photos - measure your speakers against them and test fit the speakers in the openings, and the brackets in the truck, before final assembly.

Yes, all the required mounting hardware comes with them, and they are sold as a set of two.

The 55-59 brackets are currently cut for the small back window cab only; the big window cab is a different shape and we do not have a version for it yet. On 47-54 cabs, 1947-1948 may need modification, and the brackets will not work alongside the factory in-cab gas tank.

This part is listed for 1955–1959 Chevy and GMC 3100, 3600 and 3800. The full year, make and model list is in the Truck Compatibility tab on this page. If your truck has been modified, or you are between two of the year ranges we list, send us the year, make and model and we will confirm the fit before you order rather than after.

It is a stock item and leaves our warehouse in 1-3 business days. Transit after that is typically 2-5 business days in the United States. Larger orders can arrive in more than one box on different days.

You have 30 days from delivery to return it by mail. Return shipping is on you, and the part needs to come back uninstalled and unmodified - once a panel has been trimmed or welded it cannot go back. Made-to-order items are final sale. The full terms are on our returns page.
