The crankshaft is the mechanical backbone of your engine, responsible for converting the linear energy of your pistons into the rotational force that drives your wheels. When your engine demands a rebuild, settling for anything less than a CFMoto OEM Engine Crankshaft means compromising the balance and longevity of your ride.

Available at Witchdoctors.com, our genuine CFMoto crankshafts are engineered to meet the exact tolerances required for high-torque off-road performance. Whether you are deep in the mud with a CFORCE or hauling heavy loads in a UFORCE, an OEM crankshaft ensures your engine runs as smoothly as the day it left the factory.

Why Choose a Genuine CFMoto OEM Crankshaft?

The crankshaft is under immense stress every time you hit the throttle. CFMoto Original Equipment Manufacturer (OEM) parts are designed to handle the specific harmonic vibrations and heat cycles of their proprietary engines.

• Precision Balancing: OEM crankshafts undergo rigorous factory balancing to eliminate engine vibration, which protects your main bearings and crankcase.
• Superior Metallurgy: Constructed from high-strength forged steel or alloy to resist twisting and snapping under high RPMs.
• Exact Fitment: No modifications required. These are "drop-in" replacements that maintain factory oil clearance and timing specifications.
• Reliable Oil Flow: Machined with precise oil passages to ensure consistent lubrication to the connecting rod bearings.

Frequently Asked Questions (FAQs)

What are the signs of a failing crankshaft?

The most common signs include a heavy "knocking" sound from the bottom of the engine, loss of oil pressure, or metal shavings found in your oil filter. If your engine has seized, the crankshaft is likely damaged.

Do I need to replace my bearings when I replace the crankshaft?

Yes. It is a standard industry practice to never install a new crankshaft with old bearings. Worn bearings can have uneven surfaces that will quickly score and ruin your new OEM crankshaft.

Is the crankshaft assembly sold with the connecting rods?

Most CFMoto OEM crankshafts come as a complete assembly with the connecting rods already pressed and balanced. Check the specific product listing on Witchdoctors.com to confirm the assembly details for your model.
