Thank you for purchasing a Poison Spyder Tramp Stamp for your Jeep YJ, TJ or LJ. The Tramp Stamp installs over the body sheet metal below the tailgate, finishing off your Poison Spyder body armor in style. Installation is fairly simple with the right tools and good mechanical abilities. If you are not confident in your mechanical skills, please seek the help of a professional to perform the installation. Please read through these entire instructions before proceeding with installation. 


Please check your packages immediately upon arrival to ensure that everything listed is included, and to check for damage during shipping. If anything is missing or damaged, call Poison Spyder at (951) 849-5911 as soon as possible. 

(1) Tramp Stamp
(8) 3/16” Truss head pop rivet, black


1. Park vehicle on a level surface and set the emergency brake. Remove any stickers, brackets, license plate holder or any other obstruction from the area below the tailgate where the Tramp Stamp will be installed. Clean the area, straighten any bends or creases in the sheet metal, and sand/ primer/paint any bare metal to prevent rust underneath the Tramp Stamp. 

2. Prep the Tramp Stamp for installation by painting, powder coating, polishing it or leaving it bare. The Tramp Stamp is made of aluminum plate, so it won’t rust but it will oxidize slightly over time if left bare or polished. If you paint it, thoroughly clean and lightly scuff with a sander prior to applying an initial coat of primer, followed by your paint color of choice.  

3. Hold the Tramp Stamp in place over the rectangular sheet metal section below the tailgate. There is some room for adjustment, so make sure the gaps at either side and along the top are all even while holding the Tramp Stamp in place.  

4. Use the transfer punch or fine-tip marker to mark the 8 hole locations using the Tramp Stamp itself as the template, then set the Tramp Stamp aside.  

5. Drill each of the marked hole locations with a 13/64” bit. Be careful not to let the bit “catch” and deform the sheet metal as it breaks through.  

6. Clear any burrs from the holes, then use some touch-up paint or clear coat to protect the bare metal around the edges of the holes from future rust.  

7. Place the Tramp Stamp back into position and use your pop rivet tool to install the supplied rivets through the 8 holes. Make sure the Tramp Stamp is level and centered, and begin by installing rivets on two opposite corners to securely hold the Tramp Stamp while you install the remaining rivets. 

Congratulations, you have completed the installation of your Poison Spyder Tramp Stamp!
