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.

Clutch and flywheel kit for Porsche Boxster 986 3.2L, combining a matched clutch plate, pressure plate and flywheel from Sachs for 3.2-litre Boxster S models within the 986 range.

What This Product Does This kit renews the clutch and flywheel assembly so engine torque is correctly transferred to the gearbox, with components designed to work together as a complete set for the Boxster 986 3.2L.

Functions

• Transfers torque from the engine to the transmission via a matched clutch and flywheel set
• Provides a friction surface for the clutch plate and maintains alignment between components
• Allows controlled engagement and disengagement of drive for gear changes
• Helps manage driveline vibration and smooth take-up when moving off
• Supports consistent clutch operation by pairing compatible parts in a single kit

• Clutch slip under acceleration or a rising bite point
• Judder or shudder when moving off in first gear
• Chirping, rumbling or whirring noises when the clutch pedal is operated
• Difficulty selecting gears or engaging gears smoothly
• Rattling or knocking from the bellhousing area, especially at idle
• Vibration through the driveline or pedal linked to flywheel wear

Why Replacement Matters

On ageing Boxster 986 3.2L models, clutch and flywheel wear is common due to mileage, heat and normal use. Replacing these parts together helps avoid mismatch between new and worn components and reduces the chance of having to remove the gearbox again to address related issues. Using a dedicated Sachs kit brings matched parts from a single supplier, supporting correct fitment and predictable operation once installed.

Fits

• Porsche Boxster S 986 3.2L 1999–02  (M96.21/24)
• Porsche Boxster S 986 3.2L 2003–04 (M96.21/24)

FAQs

• Q: Should I replace the flywheel at the same time as the clutch?
  A: If inspection shows wear, heat spots or excessive play, especially on a dual-mass flywheel, it is often addressed during clutch work to avoid repeat labour.
• Q: Do I need new bolts during installation?
  A: Many clutch and flywheel bolts are torque-to-yield; follow Porsche and Sachs guidance and replace any specified one-time-use fixings.
• Q: What else should be checked while the gearbox is out?
  A: Common additional checks include the release bearing and guide tube, clutch fork and pivot, and the rear main seal so potential leaks or wear points are dealt with at the same time.
