Features and Benefits of RS-644R2

  • Durability: Produced from high grade materials to stand up to frequent club and track running.
  • Performance: Helps reduce drivetrain losses for more consistent throttle response and less component fatigue.
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 difficult is installation of the RS-644R2?

Installation is straightforward with basic tools; follow standard disassembly of the RSR-020 transmission and replace the shaft, checking bearing seating and gear mesh before reassembly.

What routine checks should I do after fitting it?

After fitting, verify gear mesh, spin the drivetrain to check for binding, and recheck after a few runs for any loosening of fasteners or bearing movement.

Can I reuse stock bearings with this shaft?

Often stock bearings will work, but upgrading to fresh high quality bearings will make the most of the RS-644R2 and reduce friction under load.

Will this change handling characteristics?

Expect a firmer centre drive feel and more consistent power transfer, which can translate to improved throttle control and reduced drivetrain slop on corner exit.
