EPS IMS Bearing Upgrade
The EPS Cylindrical IMS Bearing Solution takes a different approach to traditional IMS bearing replacements. Rather than relying on a conventional ball bearing, EPS has developed a patented cylindrical roller bearing designed to better manage the forces acting on the intermediate shaft.
At RPM Specialist Cars, we’ll help you decide whether the EPS system is the right choice for your Porsche, explaining how it compares with other options, including the LN Engineering range.
What Makes the EPS Solution Different?
Unlike conventional ball bearings, the EPS design separates the radial and axial loads placed on the intermediate shaft.
Its patented thrust control system allows the cylindrical roller bearing to rotate freely without side loading, helping to spread the forces more evenly across the bearing assembly. The EPS solution is also backed by a 5-year warranty for added peace of mind.
Key Features
- Patented cylindrical roller bearing design
- Separate thrust control to reduce side loading
- Can be installed without complete engine disassembly on compatible engines
- Designed for increased load capacity compared with conventional ball bearings
EPS introduced its cylindrical bearing system in 2013 and it has become a popular choice among Porsche owners looking for an alternative to traditional ceramic bearing upgrades. The design focuses on improving load distribution while maintaining continuous lubrication, providing another proven option for protecting M96 and M97 engines.
