Kent-Moore EN-48589-A GM Crankshaft Hub Socket
For GM/General Motors.
The crankshaft and balancer are being enhanced on all 2007-later 2.8L and 3.6L HF V6. A retaining key is being added in place of the balancer relief, so existing crankshaft hub socket EN-46111 will no longer fit the crankshaft. EN-48589-A will locate on the key, and is used to turn the crankshaft during engine service.
