Service main shaft for Yokomo RS1.0

The Yokomo RS-644 Main Shaft is a service replacement crafted to preserve the RS1.0 chassis driveline geometry. It ensures reliable support for the centre pulley and the spur gear assembly and suits RSR-010 and RSR-LFGT3RTR models, making it useful for scheduled servicing or after-incident repairs.
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.

Will the RS-644 improve handling?

While the shaft itself does not change chassis geometry, a straight, unworn RS-644 helps keep consistent motor alignment which supports predictable drivetrain response and handling.

Are there upgrade options related to this part?

Upgrades usually focus on bearings, pulleys or hardened shafts. If you run high power or frequent bashing, consider matching the RS-644 with upgraded bearings and reinforced motor mount hardware.

How should I inspect the shaft after a crash?

Check for bends, wear on splines and damage to the seating faces. Replace the RS-644 if you see deformation or if gear alignment cannot be restored during reassembly.
