What is an IMS Bearing?

An IMS Bearing supports the intermediate shaft on the flywheel side of the motor. The intermediate shaft drives the camshaft directly off the crankshaft. An intermediate shaft allows for the speed of the chains to be reduced which is for the life of the chain. This type of intermediate shaft that drives the camshafts off the crankshaft has been a staple of the flat 6 Porsche engine.
