62mm Flange IMS Bearing Upgrade Kit for “Closed” Engines with Full Ancillaries – The Ultimate Eternal Fix for Porsche 987.1 Boxster / Cayman Manual Models

MUST USE OUR BORING TOOL IN ORDER TO INSTALL - the boring tool can be purchased or rented from us

This IMS bearing upgrade kit is engineered specifically for Porsche 987.1 Boxster / Cayman manual cars with M97 intermediate shaft housings. This version is the Eternal Fix, a patented and significantly stronger alternative to ball-bearing-based designs. The kit includes a 62mm cylindrical IMS bearing with thrust control, plus all required ancillaries—hardware, exhaust clamps, sleeves, seals and fittings—ensuring a complete and professional installation.

Fits:

• Porsche Boxster 987 2.7L 2005 -08/08
• Porsche Boxster 987 S 3.2/3.4L 2005-08/08
• Porsche Cayman 2.7L 987C 2006-08
• Porsche Cayman S 3.4L 987C 2005-08

Designed for “closed” engines, this IMS solution must be installed using a dedicated boring tool, allowing the bearing assembly to be pressed directly into the back of the engine without full teardown.

The Early 987.1 engines using the 62mm closed bearing are particularly vulnerable to IMS wear, lubrication issues and axial loading. The EPS cylindrical bearing design eliminates these weaknesses by separating axial load from radial load, making this the only true long-term IMS cure rather than a temporary replacement.

What This IMS Upgrade Kit Does

This advanced IMS upgrade:

• Permanently eliminates the weak factory-style ball bearing
• Uses a patented cylindrical roller bearing with dramatically higher load capacity
  
• Separates axial and radial loads to prevent premature bearing overload
  
• Improves lubrication via a dedicated oil-pressure feed kit
  
• Protects the intermediate shaft and cam drive system
• Allows installation without full engine disassembly (when used with the correct boring tool)

Includes hardware, sleeves, exhaust clamps and seals for a complete upgrade

Designed for long-term reliability and motorsport-level durability.

Why the Original IMS Bearings Fail (Especially on 62mm Closed Engines)

Typical causes include:

• Ball bearing fatigue, leading to sudden collapse
  
• Axial load overload, which ball bearings cannot handle
  
• Oil contamination or lack of sufficient lubrication
• Heat cycling and material fatigue
• Seal degradation, allowing lubrication to escape

Design limitations of the early intermediate shaft system

Closed-style engines are especially susceptible because the bearing is not easily inspectable and operates under higher load.

Why the Eternal Fix IMS Upgrade Is the Best Solution

This patented system offers:

• Over 12× the load capacity of traditional ball-bearing IMS solutions
• True separation of radial and axial loads, preventing roller overload
  
• A bearing that does not rely on side-loading, unlike conventional cylindrical or ball bearings
  
• An oil-fed outer race, ensuring stable lubrication
  
• A lifetime-capable design, not a service interval part
  
• A 5-year warranty for confidence and peace of mind
  
• Compatibility with closed engines using a precise boring tool

It is engineered to outlast the engine itself, making it the ultimate preventative upgrade for Porsche 987.1 Boxster / Cayman, manual cars.
