PLM Seat Side Mount Brackets Installation Tips

Quick answer

Install PLM seat side mount brackets by first securing the bracket to the seat, then attaching the slider assembly, and finally bolting the assembly to the vehicle floor. Pay close attention to bolt torque and orientation to avoid binding.

Installation steps

1. Attach brackets to the seat: Align the PLM side mount bracket with the threaded inserts on the side of your aftermarket seat. Use the supplied bolts (typically M8) and hand-tighten them evenly on both sides. Do not fully torque yet. Common mistake: using bolts that are too long can bottom out in the seat insert. Check thread engagement before final tightening.
2. Install the sliders onto the brackets: Slide the seat slider into the pre-drilled slots on the PLM bracket. Align the slider holes with the bracket slots and insert the provided bolts. Tighten to manufacturer torque spec (usually 20-25 ft-lb). Ensure the slider moves freely before proceeding. Checkpoint: if the slider binds, loosen the bolts and re-align the bracket. Overtightening can distort the bracket slots.
3. Mount the assembly in the vehicle: Position the seat and slider assembly over the factory mounting holes in the vehicle floor. Use appropriate grade 8.8 or better bolts and flat washers. Torque to 30-35 ft-lb. Do not use the factory bolts if they are too short for the added bracket thickness. Common mistake: reusing factory bolts that are too short. Always verify bolt length after adding brackets and sliders.
4. Final adjustments and check: Sit in the seat and adjust the slider position. Tighten the side mount bracket bolts to the seat manufacturer's spec (typically 25-30 ft-lb). Check all bolts for security after a short drive. Checkpoint: re-torque all bolts after 100 miles to account for settling.
