Upgrade the XRAY X4 with a precision 20T composite pulley

The XRAY 305579 - X4 20T Composite Layshaft Pulley is a precision-molded part made to match the X4 layshaft assembly. This 20T pulley reduces friction and rotational weight, helping deliver cleaner, more consistent power to the drivetrain.

Model Fit and Intended Use

Made specifically for the XRAY X4 2022 layout, the pulley fits the factory layshaft configuration and works with standard bearing sizes. It is a direct replacement or a simple performance upgrade for maintaining efficient drivetrain operation.

Installation and Maintenance Tips

Before fitting the XRAY 305579 pulley, clean the shaft and bearings to avoid grit or contamination. Check alignment and bearing seating during installation to ensure quiet running and long service life.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this pulley fit other XRAY generations?

It was designed for the X4 2022 layout, but it can fit other XRAY cars that use the same layshaft dimensions. Measure shaft and bearing sizes to confirm fit before purchasing.

How does a composite pulley affect handling?

A lighter composite pulley lowers rotating mass, which can slightly improve throttle response and acceleration without changing gear ratios.

What bearings should I use with this pulley?

Use quality sealed bearings that match the stock sizes for smooth operation. Regular inspection and light bearing grease can extend life under track conditions.
