A completely serviced 2.0 liter crankshaft for an M10. Bearing sizes will vary but they will not be maxed out (you will be told which sizes). The sprocket is not a part of the pricing and your crank may or may not come with a sprocket. Even if it does come with a sprocket, it may or may not be usable (The sprocket is not removed nor added for the machining process we send them as they come). Each crank receives a micro-polish, a balance, and a grind (if necessary). The core price is included, you do not need to send us your core.
