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.

IMS Intermediate Shaft Bearing Upgrade – EPS Eternal Fix (M96 / Early M97.01) Prevent future IMS-related engine damage with the EPS Eternal Fix for the well-known Porsche IMS bearing issue. Unlike common ball-bearing upgrades, EPS uses a patented cylindrical roller bearing with thrust control, engineered to separate axial (thrust) loads from radial (running) loads for long-term durability.

What makes EPS different?

Many bearing upgrades can be compromised when thrust loads act on the bearing rollers. EPS’s patented design ensures the rollers carry radial load only, while the axial load is carried around the full perimeter of the outer race. This reduces overload conditions and delivers a solution engineered to last the life of the engine. 

Key benefits

Patented cylindrical bearing with thrust control (not a ball-bearing solution)

In-car installation: designed to be pressed into the rear of the engine without engine disassembly EPS states significantly increased load capacity vs typical ball-bearing upgrades (often quoted as up to 12x)

Backed by an EPS 5-year warranty

Recommended to install alongside the Rear Main (#8) Seal and Housing

Important fitment note (997 3.8L M97.01) Engine numbers up to M97/01 68509790 use the older IMS bearing (fits). Engine number M97/01 68509791 onwards has the larger revised IMS (does not fit). Please verify engine number before ordering.
