I got tired of the tailgate slipping out of my hands and slamming down so I picked up the EZ Down Tailgate assist from Genos Garage.
Its a great little kit that comes with all the parts and tools. (rare nowdays) The only extra thing you need is a heat source for the heat shrink tubing.
All total it took me just under 15 minutes to instal. I'll hit the highlights and point out the one change I made.
First, remove the cable and the cable bolt on the truck.
Replace it with the new bolt and re-attach the cable.
Unscrew the cable from the tailgate but instead of removing the travel limit washer as in the instructions. I flattened out the limit side of the washer so that the cable would not rub against the paint. You will only flatten out the short tab. The long washer tab slips into a slot on the tailgate so it doesnt move around.
Add the damper tube to the bolt and then slip it on the tailgate mounting bolt (you added earlier. Yeah its in their instructions...)
Here is the finished result
