Description
A tailgate hinge trunnion set for 1988–1998 Chevy and GMC OBS trucks. Factory trunnions wear out, get noisy and rust; these take their place so the tailgate opens and closes smoothly every time.
On a 1988-98 OBS that sees regular use, the tailgate hinges take a beating, and worn trunnions are often what you hear when the gate rattles or groans on the way down. This kit swaps the factory pieces for stainless steel and Delrin parts that bolt into the original locations, so you can freshen up the tailgate without modifying the truck.
Features
- CNC machined from 1/8" 304 stainless steel and Delrin.
- Rust-proof 304 stainless steel construction.
- Delrin bushings for silent, smooth operation.
- Laser cut stainless steel hinge plates.
- Direct bolt-on replacement, no modifications needed.
Choose your option
- With mounting hardware
- Without mounting hardware
Order the kit with mounting hardware if you want everything in one box, or without mounting hardware if you plan to reuse what is already on the truck or source your own. Both options fit 1988-98 Chevy and GMC OBS pickups listed in our tailgate upgrades.

Tailgate Trunnion / Hinge Kit - 88-98 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.
How do I know it fits my truck?
This part is listed for 1988–1998 Chevy and GMC C1500, C2500, C3500, K1500, K2500, K3500 and others. 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.
What if it is not right for the truck?
You have 30 days from delivery to request a return. The part needs to come back new, uninstalled and in its original packaging - once a part has been trimmed or welded it cannot go back. Return shipping is at your cost, and we ask that returns come by USPS. Made-to-order, sale and clearance items are final sale. The full terms are on our returns page.
