Center Shaft: Purpose and Benefits

The Yokomo SD-644WA is a hollow graphite center main drive shaft built for RC touring drivetrains. Its hollow graphite construction reduces rotational inertia while maintaining the stiffness needed for reliable power transfer, and the matte finish minimizes distracting reflections on the chassis.

It replaces the factory center shaft in compatible DP-series Yokomo platforms and is intended as a lightweight option where lower inertia and accurate drivetrain alignment are desired. Fitment aims to be direct with minimal interference to adjacent components.

As a center drivetrain replacement, the SD-644WA suits builders seeking a lighter center shaft with a low-gloss look; during install confirm bearing seating and gear mesh to keep the drivetrain tracking true.
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.

How should I check fitment before first run?

Before powering up, mount the SD-644WA and check that bearings seat fully, then rotate the drivetrain slowly by hand to confirm there is no binding and that gear mesh remains correct.

Will the SD-644WA fit all DP-series models listed?

The part is listed for many DP-series and MRTC variants; verify the exact model code of your chassis against the compatibility list to ensure correct fitment.

Any tips to avoid driveline noise after installation?

Confirm gear backlash and bearing alignment, tighten mount points evenly, and check that the shaft spins freely by hand to reduce chatter under load.

How do I keep the matte finish looking good?

Use a soft, dry cloth to remove dust and avoid solvents; mild isopropyl wipes will work for light grime but do not scrub with abrasive materials.
