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.

Features

  • 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.

Common questions

Is trimming or drilling needed?

On the latch kits, yes. Expect to trim the tailgate itself, drill one hole in the tailgate jamb for the supplied rivnut and one in the bedside jamb for the striker mount. Templates are included in the kit and the installation template is also published as a PDF on the product page.

Do I reuse any factory hardware?

On the latch kits the factory latch hardware is still required alongside the additional hardware supplied. Everything else - latches, latch mounts, bed bracket and cable mounts, cables - is in the kit.

Will this fix a gate that will not close square?

A worn latch mechanism is the usual cause and the kit replaces it, but a sagging gate is normally the trunnions or hinges rather than the latch. If the gate drops at one end when it is closed, start with the trunnion and hinge kit for your year.

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 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.

What if it is not right for the truck?

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 part has been trimmed or welded it cannot go back. Made-to-order items are final sale. The full terms are on our returns page.
