Before You Start
- Tools needed: 12mm socket, ratchet

IMPORTANT:
To prevent cross-threading, always start bolts by hand and ensure they thread smoothly before tightening.
Step 1 – Remove Front Bolts
- Remove any plastic trim at the base of the seat.
- Remove both front factory seat bolts (12mm socket).
- Loosen the rear seat bolts (do not remove them).
Step 2 – Lift the Seat
- Lift the front of the seat by pushing back on the headrest.
- Or have a helper gently lift or pull the seat backward.
Step 3 – Install Spacers
- Place the desired number of spacers under the seat.
- Position them between the seat rails and the floor.
Step 4 – Select Correct Bolts & Install
-
Use the correct bolt length based on your setup:
- .5" shim only → use 40mm bolt
- Both shims (1") → use 50mm bolt
- Start all bolts by hand before tightening.
IMPORTANT ALIGNMENT TIP
If the seat rail holes do not line up:
- Lift the seat rail approximately ¼ inch
- Start the bolt a few threads
- Adjust the seat rails one at a time until aligned
Step 5 – Torque Bolts
- Torque both front and rear seat bolts to 27 ft-lbs.
Final Check
- Verify all bolts are torqued to spec
- Recheck torque after a few days of driving
You're done. Enjoy the improved seating position.
