Engine Main Bearing Caps And Supports
When the engine you are building has a lot of horsepower, you need to make sure the bottom end can handle the increased stress. One of the upgrades that can be installed is a heavy-duty engine bearing main cap or main cap support. These components are designed to help handle large amounts of horsepower and keep your crankshaft in the block without breaking or distortion. JEGS offers high-quality main bearing and engine block caps for many applications including Chevy, Ford, Mopar (including Hemi), and others from the best manufacturers including Milodon, Canton, PRW, Coleman, Speedmaster, and more. View our wide selection of engine main caps and supports that will help keep your engine's rotating assembly more secure within the block.
