Designed to replace your factory hinge trunnion with a stainless steel trunnion/delrin bearing on your tailgate. 
This reduces the friction while improving the opening and closing without the grind of noise that the old factory original or replacement part did while they rusted.
They are designed to replace your exsiting hinge trunnion and it just take a few minutes to replace. Its does requires the reuse of your bolts and lock washers.
If yu just purchase Trunnion ball and delrins, I would recommend that you chrome or powder caot you original hinge plates so further rusting will not occur.
We now offer stainless steel hinge plates as well. See out complete product line on the next page.
Set includes two (6 piece set) (2) stainless steel trunnions & (2) delrin bearings, (2) Stainless hinges plates.
You will need to reuse your original mounting hardware!
These are some example of the rusted items that create that aweful sound when opening and closing the tailgate.
