IMS Bearings
Filter by brand
IMSDOF9962
Product Information
Before ordering, it is necessary to identify which bearing size you need. There are two types of bearings (Single row and Double row) used in these engines. This kit comes with DOUBLE row bearing.
Fits:
Porsche 986 Boxster 1997 -2004
Porsche 996 Carrera 1997 -2004
Kit Includes:
Patented DOF Flange with anti-rust zinc plating
IMS Bearing
3 micro-encapsulated Porsche bolts
Spacer for bearing
Engine oil port adapter with crush ring
Cam Plug
3,000psi hydraulic hose
Fitting for hose
Thread locker
Installation instructions
The direct oil feed (DOF) solution uses a patent pending custom made Intermediate Shaft Flange that utilizes a direct oil feed to the original Intermediate Shaft Bearing. It uses an adapted pressure fed oil line from a positive oil pressure feed on the cylinder head directly to an opening in the custom Intermediate Shaft Flange. This feeds fresh oil directly to the open end of the IMS bearing (after removing the seal to expose the ball bearings on the IMS bearing). By using a positive oil feed from the engine's cylinder head valve cover, there will always be a consistent flow of oil directed to the open end of the intermediate shaft bearing.
This is a cost effective way to help protect against a possible IMS bearing failure, using the original bearing. The system, however can also be used when replacing the bearing with a new SKF steel ball bearing for added insurance with a new, zero mile bearing.

IMSKIT996TIP
Product Information
Contains EPS Eternal Fix replacement bearing along with all gearbox, exhaust and engine related ancillary parts you will require whilst doing the job.
Fits:
Porsche 996 C2 / C4 / C4S with Tiptronic gearbox
This IMS covers BOTH Single & Double Row IMS.
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.

About IMS Bearings
Porsche IMS Bearing Upgrades - Intermediate Shaft Reliability Solutions
The IMS (Intermediate Shaft) Bearing is a critical internal component used in many water-cooled Porsche engines to support and time the intermediate shaft that drives the camshafts. In certain Porsche engines, the original factory IMS bearing design has proven vulnerable to premature failure, which can result in catastrophic engine damage.
Available from Design911, this category features upgraded Porsche IMS bearing solutions engineered to improve lubrication, durability, and long-term engine reliability. These upgrades are essential for preventative maintenance, engine rebuilds, and performance-focused ownership.
What Does the IMS Bearing Do?
The IMS bearing supports the intermediate shaft, ensuring accurate camshaft timing and smooth engine operation.
Core Functions:
- Supports and stabilises the intermediate shaft.
- Maintains precise camshaft timing.
- Transfers rotational forces within the timing system.
- Ensures smooth engine operation at all RPM ranges.
- Plays a vital role in overall engine reliability.
A healthy IMS bearing is fundamental to safe Porsche engine operation.
Why Do IMS Bearings Fail?
Certain factory IMS bearings were designed as sealed units
with limited lubrication, making them susceptible to wear and failure over
time. Common causes include:
- Insufficient lubrication of sealed bearings.
- Bearing seal degradation allowing contamination.
- Extended service intervals and infrequent oil changes.
- High mileage and age-related wear.
- Increased load from spirited or track driving.
When an IMS bearing fails, debris can circulate through the engine, often leading to complete engine failure.
Why Upgrade the IMS Bearing?
Upgraded IMS bearing solutions are engineered to address the weaknesses of the original design.
Upgrade Benefits:
- Improved lubrication through open or oil-fed designs.
- Stronger bearing construction and materials.
- Significantly reduced risk of catastrophic engine failure.
- Ideal for preventative maintenance during clutch or engine work.
- Long-term peace of mind for Porsche owners.
Upgrading the IMS bearing is one of the most important reliability improvements available for affected Porsche models.
Highlights
- Upgraded Porsche IMS bearing solutions
- Designed to improve lubrication and durability
- Essential reliability upgrade for susceptible engines
- Ideal for preventative maintenance and rebuilds
- Reduces risk of catastrophic engine failure
