Description
Tailgate trunnions for 1947–1953 GMC and Chevy trucks, CNC machined from 6061 billet aluminum. The two-piece design runs on Delrin bushings instead of the metal-on-metal arrangement the factory used, so the gate swings smoothly instead of grinding.
They are a direct upgrade for 1947-53 Advance Design pickups where the tailgate grinds every time it opens. Because the gates on these trucks are not all the same, the kit includes thin and thick nitrile O-rings to take up the difference between factory and aftermarket tailgates.
Features
- CNC machined from 6061 billet aluminum.
- Two-piece design with Delrin bushings.
- Nitrile O-rings included to account for variation between factory and aftermarket tailgates.
- Stainless steel mounting hardware included.
- Sold as a pair.
In the kit

- 4x thick nitrile O-rings

Sold as a pair with the stainless hardware listed above, the trunnions cover both sides of the gate on a 1947-53 Chevy or GMC truck. If you are running a billet look elsewhere on the truck, they match the rest of the LS Fabrication billet aluminum line.

Billet Tailgate Trunnions - 47-53 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 1947–1953 Chevy and GMC 3100, 3800 and Suburban. 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.

These guys are awesome!!!
International Customer, product arrived within 10days from dispatch. Product is everything that was advertised and quality as usual is exceptional…
LS Fab is great and honest company! I recently order some parts from them. Shortly after I received an email from UPS that the package was damaged. For several days nothing came of it. I contacted LS Fab through their website with regards to the shipment. The next morning I received an email from them saying that they were attempting to find out what happened to the shipment. After repeated emails LS Fab stepped up and sent a second package which I have since been received. They are hardworking, punctual and thorough. I look forward to doing business in the future. Very high quality parts!
