Is my IMS Retrofit or RND RS Roller Bearing kit due for replacement ?
I already have LN Engineering’s kit installed in my car. How will I know if my IMS Retrofit™ or RND RS Roller Bearing needs replacement?
Use our new IMS Check online tool.
Search LN Engineering’s IMS product registration database by IMSR / IMSS Serial Number or your Vehicle’s Identification Number. If your installation was registered with us, you will receive detailed information about your bearing kit type, production and installation date, and recommended service interval.
