Description
Zinc-plated trunnions are what makes an old squarebody tailgate groan and hang up. This six-piece set swaps them for stainless, so the gate on your 1973–1987 Chevy or GMC opens smoothly and the hardware stops rusting.

- Six-piece set, made in the USA.
- Trunnions CNC machined from 316 stainless steel and Delrin.
- Hinge plates laser cut from 304 stainless steel.
- Direct replacement for the noisy zinc-plated factory trunnions.
Choose your option
- Year: 1973–74, 1975–80 or 1981–87.
- Type: removable fleetside, anti-theft non-removable fleetside, or stepside.
Fitment notes
The stepside version includes the trunnion bushing only, and is used with your stock tailgate bracket.

Tailgate Trunnion / Hinge Kit - 73-87 GMC Chevy Truck
Common questions
Is it a bolt-on?
Yes. It replaces the factory trunnions and goes on where the originals came off.
Will it quiet the tailgate down?
That is what it is for. The trunnions run on Delrin, so the gate opens and closes quietly instead of grinding, and the metal parts are stainless steel or billet aluminum, so they do not rust.
Is mounting hardware included?
It depends on the kit - the Features list on this page says whether hardware is included, optional or reused from your truck.
What does the stepside version include?
The trunnion bushing only. It is used with your stock tailgate bracket.
How do I know it fits my truck?
This part is listed for 1973–1987 Chevy and GMC C10, C20, C30, Sierra and Silverado. 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.
How long before it ships?
It is a stock item and generally ships within 1-3 business days. Carrier transit time is on top of that, and larger orders can arrive in more than one box on different days.

1984 GMC C2500. Easy install and works great. Quieted down the tailgate. I did the trunnions, cables, and strut for mine and it really got rid of all the rattles. Awesome kit and great customer service.
