The crankshafts on 924s and 944ss are very strong and reliable units that will last a long time if cared for properly. However, if yours needs to be replaced due to a bearing failure or just a low oil pressure problem, we offer rebuilt units at a fraction of the new cost. All rebuilt crankshafts are magna-fluxed to check for cracks and are carefully reground. Specify year and model. All cranks are sold on exchange basis with a core charge, refundable upon receipt of your useable core.
