Instruccions d'instal·lació
Installation typically takes approximately 1 hour. It is recommended to perform this installation on a clean, flat surface.
Eines necessàries:
- Conjunt de claus d'endoll
- Clau dinamométrica
- Basic Hand Tools (e.g., pry tool, screwdriver)
Passos d'instal·lació:
- Preparar el vehicle: Ensure the vehicle is off and the parking brake is engaged. Remove any items from under and around the seat.
- Remove Existing Seat: Locate and remove the bolts securing the front driver or passenger seat to the vehicle's floor. Carefully disconnect any electrical connectors under the seat (if applicable) and remove the seat from the vehicle.
- Identify Bracket Components: The kit includes two main adapter brackets (one for each side of the seat) and four smaller mounting plates. Note that one of the main brackets may have an offset bend to accommodate asymmetrical mounting points in the vehicle. Ensure you identify the correct bracket for the driver or passenger side and its proper orientation (e.g., the offset bracket typically goes towards the center console/shifter side).
- Install Adapter Brackets to Vehicle Floor: Position the main adapter brackets and smaller mounting plates onto the vehicle's floor mounting points. It is often easier to secure the adapter brackets to the vehicle floor first, before attaching them to the seat. Loosely install the provided hardware or reuse original hardware if compatible. Ensure all bolts align correctly with the vehicle's mounting holes.
- Verify Bolt Compatibility: Some vehicle models may have varying bolt sizes for seat mounts, particularly for safety-related points like seatbelt anchors. Verify that the provided hardware is compatible with all mounting points. If a specific bolt (e.g., a larger T50 Torx bolt) from the original setup does not fit the adapter bracket, ensure proper fitment or consult a professional.
- Mount the Seat onto Adapter Brackets: Carefully place the seat back into the vehicle, aligning its mounting points with the newly installed adapter brackets. Loosely install the remaining hardware to secure the seat to the adapter brackets.
- Tighten All Hardware: Once all bolts are loosely in place and alignment is confirmed, progressively tighten all bolts, starting from the vehicle floor mounts and then the seat mounts. Ensure even tightening to prevent binding or stress on the components. Refer to your vehicle's service manual for specific torque specifications if available.
- Reconnect Electrical (if applicable): Reconnect any electrical connectors that were detached from under the seat.
- Prova de funcionament: After installation, test the seat's forward and backward sliding mechanism to ensure smooth operation. Verify that the seat is firmly secured and does not wobble.

Funcionament
The u-Box Seat Adapter Bracket provides approximately 4 inches of additional legroom from the stock seat position. Once installed, the seat's original sliding mechanism remains fully functional, allowing you to adjust the seat's position forward and backward as needed. This allows for a more comfortable driving or riding experience, especially for taller individuals.

Manteniment
To ensure the longevity and continued safe operation of your u-Box Seat Adapter Bracket, periodic maintenance is recommended:
- Inspeccionar els elements de fixació: Periodically check all mounting bolts (both to the floor and to the seat) for tightness. Vibrations from driving can sometimes cause bolts to loosen over time. Re-tighten any loose fasteners to ensure the seat remains securely mounted.
- Components nets: The steel brackets can be wiped clean with a damp cloth to remove dirt or debris. Avoid using harsh chemicals that could damage the powder coat finish.
- Comproveu el desgast: Inspect the brackets for any signs of wear, corrosion, or damage. While constructed from durable steel, extreme conditions or impacts could potentially affect their integrity. Address any issues promptly.
Resolució de problemes
Si teniu problemes durant o després de la instal·lació, tingueu en compte el següent:
- Difficulty Aligning Bolts:
Possible causa: Brackets are incorrectly oriented or not fully seated.
Solució: Double-check the orientation of the main adapter brackets (A1 and A2, noting any offset) and the smaller mounting plates. Ensure they are placed correctly for the driver or passenger side. Loosely start all bolts before fully tightening any one bolt, which allows for minor adjustments. - Seat Binding or Not Sliding Smoothly:
Possible causa: Brackets are not perfectly aligned, or bolts are over-tightened unevenly.
Solució: Loosen all mounting bolts slightly and gently shift the seat to ensure it sits squarely on the brackets. Re-tighten bolts evenly and progressively. Verify no obstructions are interfering with the seat's sliding mechanism. - Incompatible Bolt Sizes:
Possible causa: Vehicle's original mounting bolts differ from the provided hardware.
Solució: If original bolts are required for specific mounting points (e.g., larger T50 Torx bolts for seatbelt anchors), attempt to use them. If the bracket holes are too small for original bolts, or if modifications seem necessary, it is recommended to consult the manufacturer or a professional mechanic for guidance. Avoid forcing components. - General Installation Difficulties:
Possible causa: Unfamiliarity with vehicle mechanics or specific model variations.
Solució: Refer to online resources or videos for additional visual guidance. If issues persist, consider seeking assistance from a qualified automotive technician to ensure safe and proper installation.
