LN ENGINEERING Single Row Pro IMS Retrofit 106-08.2.2 Intermediate Shaft IMS Bearing Update Kit Fits model year 2000 through 2005 Porsche Boxster and 996 models with the factory single row bearing. Please note that model year 2000 or 2001 engines may have either a dual row or single row bearing from the factory, so you need to verify which bearing is actually needed before purchasing. Unique approach and design of the IMS Single Row Pro allows installation of a dual row bearing in the space of a single row. Replaces original Classic Single Row IMS Retrofit 106-08.2 with superior dual row bearing design. A single row flange measures 19.27mm deep and a dual row flange measures 13.34mm deep. By verifying these measurements you can determine which bearing your engine has. Please also note that if your vehicle has a replacement engine, it will have whichever bearing was currently being used by Porsche during that specific model year.WHY BUY AN IMS RETROFIT FROM LN ENGINEERING?As of 2020, with 35,000 IMS Retrofit and 3000 IMS Solutions installed since 2008, our IMS bearing replacements are the most trusted and used by hundreds of independent mechanics and dealerships worldwide.WHY DO IMS BEARINGS FAIL?Lack of lubrication as a sealed bearing was used by the factory. The IMS is submerged in engine oil, so elimination of the grease seal allows proper lubrication of the new bearing. No forced oiling is required! Insufficient load capacity. The factory single row bearing had high failure rate of 8% according to the Eisen class action lawsuit compared to the factory dual row's 1% failure rate under warranty. The factory did not supply a service interval, replacement, or tools and procedure for changing the original bearing out.The original bearing should have had a service interval! The Single Row Pro IMS Retrofit has a 6 year or 75,000 mile service interval, whichever comes first.IMS RETROFIT AS PREVENTATIVE MAINTENANCEIMS replacement takes an average of 10-14 hours and requires the transmission to be removed. Tiptronic 911 models require the engine and transmission to be removed as a complete unit to be able to separate engine and gearbox. Typically coupled with clutch and other maintenance such as replacement of RMS, AOS, Water Pump, Dual Mass Flywheel, etc. If an engine failure occurs, rebuilds take 60+ hours and can cost tens of thousands of dollars to fix. Once the IMS bearing has started to fail, it cannot be replaced safely as wear metal from the original bearing can damage the replacement bearing or other internal engine components. Engines must be pre-qualified prior to bearing replacement.ALL OTHER BEARING REPLACEMENTS ARE JUST IMITATIONS.All genuine LN IMS Retrofit kits come laser etched, engraved, and serial numbered to validate their authenticity and feature custom-made, ceramic hybrid ball bearings made exclusively for LN Engineering.
