These are the ultimate upgrade over factory original trunnion hinge sets on the market today. They are manufactured with machined 303 stainless steel and Delrin which is the best corrosion resistant material to prevent rust. Does your tailgate rattle around or do you hate that grinding sound while you open or close your tailgate? Do you notice rust from the hinge supports or does your tailgate hang up while you open and close it? I have the solution and the fix, and you'll love them. They're made to fit your original stock and remanufactured tailgates so no need for greasing the trunnions any longer! There could be some small modifications you might need to make to your Delrin bearing to make it fit correctly on your tailgate. Instructions are included with each purchase!

**Alert update**
Material increases again due to COVID-19 & the continued Russia conflict. The material to make these items are now harder to find and purchase at a cheaper price. If the material comes down in the future, I will reduce the cost to purchase. So Sorry!

Materials used:
All Stainless-steel parts are made of 303 Stainless Steel is very similar in properties to that of 304 Stainless Steel, however 303 has an addition of sulfur for better machining characteristics. 303 Stainless Steel is Corrosion resistant to temperatures of 1500 Degrees or more. It is used in screw machines, food processing equipment, marine applications, and some aerospace application. 303 offers a good corrosion resistant to reduce rust.
Delrin is an Acetal AF blend, supplied as a 2:1 blend of Acetal AF-100 and Acetal 150 resins, has excellent sliding/friction properties. Bearings made of Acetal AF blend can operate at higher speeds while exhibiting reduced wear. These bearings are also essentially free of slip-stick behavior because the static and dynamic coefficient of friction are closer than with most plastics. Acetal AF blend retains 90% of the strength that is inherent in unmodified Acetal.
• High hardness and stiffness
• Very high mechanical properties
• Excellent creep resistance and dimensional stability
• Excellent dialectical properties
• Low coefficient of friction

Work in progress Pending these new products in the near future.
After removing your tailgate from the truck, you will have two (2) trunnions hinges, one for each side.
Remove the bolt from each the hinge plate and replace each trunnion ball/pivot with the new Stainless steel Trunnion ball/pivot. Be sure to use antilock/stainless steel lube so you would be able to remove to bolt in the future.
On the tailgate before installing the female Delrin. Make sure all debris, paint, dirt, etc. is removed and clean before Installing. Install the Delrin bearing flush with bevels on the outside at each end of the tailgate as seen in the picture below. Each tailgate could have changes over the years so there might be small modification to make to the Delrin part so it would fit correctly and flush. (Minor sanding or grind to make it fit properly) Might need to tap it into place with a light hammer. It shouldn't fit very tight, just enough so it won't turn in place. The flat edges prevent it from spinning or turning in place. Instructions will be sent with the product for further help.
