Note: The database is provided as-is and contains all production log records and customer registration records that were submitted to us. Listings in the database do not confirm warranty status. A considerable number of customers and shops fail to register their installation properly with us, therefore we cannot guarantee the accuracy or completeness of the database provided here.
It can take up to 90 days to for the new registrations be processed and the online database updated with most recent submissions. Incomplete registrations will not be processed subject to notification of the customer and compliance with installation and registration requirements.
How do I find my IMS Retrofit or IMS Solution serial number? >

Look for an IMS / LN Engineering tag on your car.
Common locations are:
- door (by the VIN sticker)
- door jamb
- engine compartment (near oil change stickers)
- engine lid (911®)
- rear trunk lid (Boxster®)
- next to the emissions label
- near build code options sticker
Multiple or inaccurate VIN search results? >
Duplicate last six numbers of the VIN are not uncommon from year to year and/or between models, so it is required to match up the year and approximate mileage to make sure any provided database results match your car.
If the year and mileage of a vehicle with the same last six of the VIN do not match the search results, and there’s no IMS serial number tag on the vehicle or documentation to support the bearing has been replaced, it likely has not been changed.
If two or more cars bearing the same last 6 digits of VIN were registered, they will both show in the search results.
If duplicate entries are found with the same year, contact LN Engineering by creating a support ticket at support.lnengineering.com. We will attempt to pull the original registration to see if the full vin or any other information was provided at time of registration, however in most cases, if a vehicle does not have an IMS Retrofit or IMS Solution serial number affixed or there is no documentation of an install, the IMS bearing is likely to be original and still needs to be replaced.
