IMS Bearing Upgrade Kit with Full Ancillaries – Essential Reliability Upgrade for 986 Boxster 2.5ltr with Manual Gearbox
This IMS bearing upgrade kit includes everything
needed to replace and enhance the intermediate shaft bearing in the Porsche 986 Boxster 2.5ltr with M96 engines. This complete
package includes the upgraded bearing assembly, new hardware, seals, exhaust
clamps, sleeves and all required ancillaries to streamline installation.
Fits:
- Porsche Boxster 986 2.5L 1997-99
What the IMS Bearing Upgrade Kit Does
This complete kit:
- Replaces
the vulnerable original IMS bearing with a fortified,
precision-engineered alternative
- Reduces friction and improves lubrication stability
- Protects the intermediate shaft from premature wear
- Prevents metal debris contamination inside the engine
- Restores confidence in long-term engine reliability
- Includes all necessary hardware, clamps, sleeves and seals for a seamless installation
Designed to meet the demands of both road use and high-performance driving.
Why IMS Bearings Fail in Porsche M96 Engines
Common causes include:
- Lubrication
starvation, leading to ball bearing scoring
- Seal
degradation, causing grease loss and overheating
- Contaminants entering the bearing assembly
- High
engine speeds, accelerating wear
- Age-related material fatigue
- Inadequate internal lubrication flow in the early intermediate shaft design
Symptoms are often subtle—or non-existent—until severe engine damage has occurred.
Why the IMS Bearing Should Be Upgraded
Upgrading the IMS bearing provides:
- Prevention of catastrophic bearing failure
- Significant extension of engine lifespan
- Peace of mind for owners of 986 Boxster models
- A stronger, more stable bearing with improved lubrication path
- Reduction in maintenance costs over time
- A complete installation solution thanks to included ancillaries
This kit is essential for any Porsche owner planning long-term stewardship, spirited driving, or engine rebuild work.

IMS Eternal Fix retro fit kit installs in-car without removal or disassembly of the engine required. The Cylindrical Bearing with Thrust Control design has a load capacity 5 times greater than the inferior, failure prone, Ball Bearing solutions on the market!
Why Cylindrical is Best?
Cylindrical Bearings have very high load bearing capacity, 5 times more than Ball Bearing. Cylindrical Bearings are used in, High Temp & Low Viscosity Lubrication such as Automatic Transmissions. They can carry extreme lateral pressure without wear to the friction surfaces. This is because the bearing friction surface is flat not concave.
