139QMB Naraku Performance Parts Crankshaft Heavy Duty with 16 tooth oil pump driven sprocket for GY6 139QMB/QMA 50cc Engines

Naraku crankshaft in OEM-quality to match Japanese and Taiwanese alternatives. Kitted with high quality, heavy duty quality bearings which allows for longer service life and durability, far superior to low cost Chinese cranks.

The quality is reflected in the price, but nothing is gained from using cheap parts, there is nothing more annoying than pushing your machine home following big end failure.

Matches design and size of the original with a little extra making it a perfect choice as a standard replacement or furthermore, a perfect match up for the larger cylinder capacity kits. Supplied pre-assembled with pressed bearings.
Along with the Top Racing crank, this is our favourite and when it comes to value for money, this is top choice.

Oil pump drive: 16 tooth, it is very important that you check this matches your current oil pump drive as your drive may have a 22 tooth drive cog.
