Seat Jackers Installation Instructions
Before You Start
- Estimated install time: 15–30 minutes
- Tools needed: Socket wrench + hex/Allen key
- We recommend using a helper for easier seat lifting
IMPORTANT:
To prevent cross-threading, always start bolts by hand and make sure they thread smoothly before tightening.
Step 1 – Remove Front Seat Bolts
- Remove any plastic trim covers at the base of the seat
- Remove both front factory seat bolts
- Loosen the rear seat bolts (do NOT remove them)
Step 2 – Lift the Seat
- Gently lift the front of the seat by pushing back on the headrest
- Or have a helper pull from the rear seat area
Step 3 – Install Base Shim
-
Take the shim with:
- One countersunk hole
- Two threaded holes
- Position it on the floor with the rounded edge facing forward
- Install using the provided M10 x 1.25 x 30mm flange bolts
- Apply Blue Loctite
- Hand thread first, then torque to 30 ft-lbs
Step 4 – Install Second Shim
- Take the shim engraved with “Seat Jacker”
- Use two M8 flange bolts to attach it to the other shim
- Apply Blue Loctite
- Snug them down first (do not fully torque yet)
- Set the seat leg back down and align the holes
- Once aligned, torque bolts to 20 ft-lbs
Step 5 – Reinstall Seat to Seat Jacker
- Lower the seat back into position
-
Using:
- M10 x 20mm cap head bolt
- Washer
- Blue Loctite
- Attach the seat leg to the Seat Jacker
- Start bolts by hand to avoid cross-threading
- Torque to 30 ft-lbs
IMPORTANT ALIGNMENT TIP:
If the holes don’t line up:
- Lift the seat slightly (~¼ inch)
- Start the bolt a few threads
- Adjust seat rails side-to-side as needed
- Make sure rear bolts are still loose enough to allow movement
Step 6 – Reinstall Trim
- Reinstall any plastic trim pieces removed earlier
Final Check
- Double check all bolts are torqued to spec
- Recheck torque after a few days of driving
You're done. Enjoy the improved seating position.
