The Main Bearing Set is a replacement for the original Porsche crankshaft main bearings used in 911 and 914 engines. These standard-size bearings are manufactured to exact OEM tolerances, providing a perfect fit, proper crush, and ideal oil clearance for stable lubrication and crankshaft alignment. The set includes all main bearing shells required for a complete rebuild of one engine, providing smooth, quiet rotation and factory-spec oil pressure.

Main bearings wear over time due to heat, load, and oil pressure fluctuations. Worn bearings can cause low oil pressure, crankshaft vibration, or bearing noise.
Replace these bearings:
• During a full engine rebuild or bottom-end overhaul
• When oil pressure drops or metal particles appear in the oil
• As part of preventative maintenance on high-mileage or vintage engines
New bearings restore precise crankshaft support, improve lubrication stability, and extend engine life.
