    Key Features

    • Consistent tension: Maintains optimal belt tension for precise valve timing.
    • Premium bearings: Sealed to resist dirt, heat, and moisture.
    • OE fitment: Direct replacement with exact dimensions and mounting points.

    When to Replace

    • At manufacturer’s timing belt change interval (often 60,000–100,000 miles or 5–7 years).
    • Noisy or rough pulley bearing.
    • Visible damage or misalignment.
    • Whenever replacing the timing belt for preventative maintenance.
    Tip: Always replace the tensioner pulley along with the belt and idlers to avoid premature failure.

    How to Fit (Universal Guide)

    1. Preparation: Engine cold, battery disconnected. Refer to the timing diagram.
    2. Remove covers & belt: Release tension and remove the timing belt.
    3. Unbolt old pulley: Remove mounting bolt(s) and pulley.
    4. Inspect mount: Clean surface and check for wear.
    5. Install new INA pulley: Torque bolt to manufacturer’s specification.
    6. Reinstall belt: Align timing marks and set tension according to service manual.
    7. Test run: Rotate engine by hand, then start and check for correct operation.

    Always follow the workshop manual for torque values and procedures to avoid engine damage.

    Yes! We’re constantly expanding our product range and catalog. If you can’t find the part you’re looking for, please contact us. We work with several manufacturers and may be able to source the part for you.

    Parts do not come with additional items like fitting kits or gaskets unless it is clearly specified in the Part Details section of the product page.


    Brake Discs: Most standard brake discs are priced individually, but for safety reasons, they must be purchased in pairs. When required, we will automatically set the quantity to 2 in your basket.
    Brake Pads: These are sold as a set (either front or rear), so one box is enough for two discs.


    The Compatibility Table can be found on each product page, usually below the main product description. Look for a tab or heading labeled Compatibility.
