Porsche IMS

Porsche IMS, or Intermediate Shaft Bearing, is a component found in select Porsche models produced from 1997 to 2008. It plays a crucial role in ensuring smooth engine operation and precise timing. However, some IMS bearings may experience premature wear, leading to potential engine issues.

To address this concern, aftermarket solutions and upgraded bearing designs have been developed, offering enhanced durability and reliability. These solutions provide Porsche owners with added confidence and peace of mind, mitigating the risk of IMS bearing failure.
It's important to note that not all Porsche models or engines are affected by this issue, and Porsche has implemented design improvements in newer generations of their engines to minimize the likelihood of such failures.

Experience Porsche with peace of mind, knowing that our IMS solutions deliver increased durability and reliability, safeguarding your driving pleasure and protecting your investment.

Problem: IMS failure.
Solution: IMS

Why do IMS bearings fail?
  • Lack of lubrication (sealed bearing was used)
  • Insufficient load capacity (factory single row bearing had high failure rate of 8%)
  • The factory did not supply a service interval, replacement, or tools for changing the original bearing out – bearing should have had a service interval!
IMS RETROFIT™ as a preventative maintenance:
  • IMS replacement takes an average of 10-14 hours.
  • Typically coupled with clutch and other maintenance.
  • Engine rebuilds take 60+ hours and can cost tens of thousands of dollars.
  • 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.
