📋 Product Overview

This is a C50 Crankshaft Connecting Rod, suitable for various horizontal engine vehicles, including mopeds, Cub series motorcycles, dirty bikes, and ATVs. The connecting rod is one of the core moving parts of the engine, connecting the piston to the crankshaft and converting the reciprocating motion of the piston into rotational motion of the crankshaft. Manufactured from high-quality alloy steel through precision forging, machining, and heat treatment, it offers excellent strength, fatigue resistance, and wear resistance, ensuring long-term stable engine operation.

Applicable Engine Models:

139FMB 147FMD 147FMF 150FMG & other similar horizontal engines

🔧 Quality Assurance: Made from high-quality alloy steel with precision forging. Strict quality control ensures each connecting rod's dimensional accuracy, strength, and parallelism meet OEM specifications.
