NCY Performance Secondary Slider Rear Pulley Sheave for GY6-50 139QMB


In stock (can be backordered)


Very nice quality secondary sliding sheave by NCY for the GY6 50 engine.

The benefits of a good quality torque sheave are mind blowing and little known.

Stock sheaves have poorly designed and manufactured cam spirals in them and cause poor “shifting”. By replacing the stock unit with a good one you will see very much increased acceleration and response from your CVT system, as well as longer life.

Great value!
