Enginetech Main Bearings

Enginetech main bearings for GM engines are replacement crankshaft main bearings (also called engine main bearing sets) made to restore smooth, reliable crankshaft support during an engine rebuild or overhaul. Each bearing sits between the crankshaft journals and the engine block. It carries rotating loads and keeps a controlled oil film in place to reduce friction and wear.

Key Features:

• Designed as direct-fit replacement bearings for GM engine applications
• Precision-manufactured bearing shells for consistent wall thickness and proper oil clearance
• Durable bearing materials chosen to resist fatigue, wear and heat under continuous load
• Oil-groove and locating-tab designs that help with proper installation and lubrication
• Available in multiple sizes, including standard and undersize options, so you can match them to your crankshaft journal condition

Enginetech is a recognized name in engine rebuilding components, and its parts are built for professional engine builders and DIY rebuilders alike. For best results, measure the crankshaft journals and check oil clearances during assembly. Use fresh engine oil or assembly lubricant on the bearings before installation.
