Desert Does It will not be liable for any loss, damage, or injury directly or indirectly from the use or the inability to determine the use of these products. Before using or installing, the user shall determine the suitability of the products for its intended use, and the user shall assume all responsibility and risk in connection therewith. Any modifications to your vehicle are done at your own risk.


General Note: To help prevent cross threading during installation, we recommend verifying bolts and threads by taking the applicable bolts and threading them in by hand to the corresponding hole. Seat Jackers are sloped so make sure the larger side is facing forward. Also, if installing both front and rear Seat Jackers make sure the numbers are facing forward. Same steps apply for the rears, just reversed.


  • Step One: Remove any plastic trim at the feet of your seat. Remove both front factory seat base bolts and loosen the two rear seat bolts but do not remove them.
  • Step Two: Lift the front seat by pushing back on the headrest or by asking a helper to pull from the back seat.
  • Step Three: 3/8 Inch Lift/One Seat Jacker Shim - Choose the Long Slotted Seat Jacker and place it under each front seat rail in between the rail and your carpet. The Long Slotted Seat Jacker is for the optional MMP, do not discard. Move to step four. (Shims are tapered so the thicker end will face the front).
  • Step Three: ¾ Inch Lift/ Two Seat Jacker Shims - Take the Long Slotted and the Middle Seat Jacker and stack them together. The Shims are notched and will nest together. At the front seat mounting point, place the Seat Jacker stack in between the front seat rail and your carpet. Move to step Four.
  • Step Three: 1 ⅛ Inch Lift/Three Seat Jacker Shims - Take the Top and Middle Seat Jacker and stack them. The Long Slotted Seat Jacker will go on the bottom and can be lined up (front to back) as desired. At the front seat mounting point, place the full Seat Jacker stack in between the front seat rail and your carpet. Move to step Four. 
  • Step Four: If using one or two Seat Jackers, use the provided 40mm hex head bolt. If using all three Seat Jackers, use the provided 60mm hex head bolt. Take the correct hex head bolt and thread it through the seat rail, through the Seat Jackers, and into the floor of the vehicle. *IMPORTANT – IF THE SEAT RAIL HOLES DO NOT LINE UP, LIFT UP THE SEAT ABOUT 1/4 INCHES AND THREAD IN THE BOLT A COUPLE OF THREADS. IF NEEDED ADJUST THE SEAT RAILS ONE AT A TIME TO GET EVERYTHING TO LINE UP AND CONFIRM REAR SEAT BOLTS ARE LOOSE ENOUGH.
  • Step Five: Torque two front bolts and two rear bolts to 30 ft-lbs.
  • Step Six: Reinstall any plastic trim pieces that were removed in Step One.
