ITM Main Set

ITM main bearing sets, also called engine crankshaft main bearings or crank main bearings, support the crankshaft inside the engine block. They keep the crankshaft turning smoothly and hold a thin film of oil between the moving surfaces. This product line is for engine rebuilds and repairs.

Key Features:

• Replaces worn main bearings in the engine's rotating assembly
• Made for the precise fit and clearances an engine rebuild needs
• Helps keep oil pressure steady and reduces friction and wear on the crankshaft journals
• Sold in sizing options to match the crankshaft's journal condition
• From ITM, a supplier of engine rebuild components

Fitting new main bearings during an overhaul helps restore engine performance and extends the life of the crankshaft and block. Choose the variant that matches your engine and crankshaft journal size.
