Fitment and compatibility notes

The Yokomo SD-644WA is a hollow graphite center main drive shaft designed for use in RC touring drivetrains. Its hollow construction reduces rotating inertia while the graphite elements retain sufficient stiffness for reliable power delivery, and the matte finish avoids bright reflections on the chassis.

This shaft is intended to replace the standard center shaft on compatible DP-series Yokomo platforms and is suited to builders prioritising lower rotating mass and steady center alignment; always check fitment details before installation.

The SD-644WA is aimed at hobbyists seeking a lighter centre drivetrain element with discreet visuals; confirm bearing seats and gear mesh during fitting to protect drivetrain alignment and function.
Remark :
Due to limited stock availability, please notice that some Yokomo 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.

Does the SD-644WA require different bearings?

In most cases the SD-644WA uses the same bearing sizes as the standard shaft, but always compare the bearing inner diameters and seat dimensions during trial assembly to be certain.

What should I look for when confirming compatibility?

Match your chassis model code against the compatibility list and verify physical clearances around the center shaft to ensure no contact with nearby components.

How do I prevent misalignment after fitting?

Check bearing seating depth, secure mounting hardware evenly, and spin the assembly by hand to detect uneven drag or binding before track use.

Is the SD-644WA suitable for daily club use?

Yes—when installed correctly and inspected periodically, the SD-644WA performs well for regular club and competitive running, offering reduced rotating mass without sacrificing required rigidity.
