Good To Know

Q: Does this assembly come as one complete unit? A: Yes, it ships as a complete crankshaft assembly so the rotating core can be installed as a single unit during a bottom-end rebuild.

Q: Should I check fitment before ordering? A: Confirm your engine displacement and model year against this listing, since the 1503 HO crankshaft is specific to that platform.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
