Doors are what most people would call deceiving. You see, when one reaches for a door handle on a Tri-Five Chevy truck, all it takes is a simple push of a button and the door opens with ease. However, the truth of the matter is that those doors aren't necessarily light; in fact, they are rather heavy, especially when the window, door internals, door panels, and possibly radio speakers are installed. What makes them so easy to open is the hinges, which allow them to swing freely, but even hinges begin to have a problem doing their job after years of wear and tear.
With over 50 years of hanging and holding up those heavy doors, the hinges begin to sag. Usually it doesn't hurt the hinge's function too much, but what a sagging hinge affects most is the door's fitment. Because of the sagging hinges, the gaps around the door begin to open up in some areas and close in others. All in all, it makes for a sight one doesn't want to see on one's truck.
In the years prior, the common way to fix a sagging door was to replace the worn-out hinge with a less worn used hinge. However, to get the job done in this day and age, it's just like almost every other task on a classic truck: one relies on the aftermarket industry. Being one of the largest providers of Chevy and GMC truck parts, it was only a matter of time before Brothers Classic Chevrolet & GMC Truck Parts added part numbers for new Tri-Five hinges. And that day has now come. Brothers now offers new correct reproductions of the door hinges for '55-59 Chevy and GMC trucks. The complete hinge assemblies are an easy replacement for the worn and sagging, not to mention damaged or missing, door hinges. Brothers manufactures both the upper and lower hinges so users can get the correct fitment and installation GM intended. The upper hinge even includes the door check assembly, which holds the door in the fully opened position.
Here's the new set of hinges from Brothers. They are designed to replace the original hing
