The Story
This Timken pinion shaft bearing is a direct-fit replacement for Porsche 356 and 911/912 applications listed in the fitment table below. It supports the pinion shaft within the differential assembly, helping maintain proper gear alignment and smooth rotation under load. When these bearings wear, you start to see noise, vibration, or inconsistent gear contact, especially under load.
Timken is a well-established manufacturer of bearings used in OEM and high-load drivetrain applications. Their components are built to handle sustained loads, maintain proper tolerances, and perform consistently in critical assemblies like Porsche differentials and transaxles.

Fitment & Compatibility
Use the fitment table below to confirm exact Porsche model and year coverage. Early Porsche applications can vary depending on transmission type and submodel, so it is worth matching details carefully.
If you are unsure about fitment, send us your VIN and we will help verify it. At PMB Performance, we’ve been working with Porsche drivetrain and brake systems for over 20 years, and we still treat fitment questions like they matter.
