Good To Know

Q: Does this include connecting rods? A: Yes, this is listed as a complete crankshaft assembly, which typically includes the crankshaft and connecting rods. Confirm component contents with the seller before buying.

Q: Can I install this without checking my engine serial number? A: It is wise to verify your engine code and serial number first, because 1503 variants can differ in internal specs. Matching the assembly to your exact engine avoids fitment problems.

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