Straightforward RSR-020 Upgrade with Yokomo RS-644R2

For modelers pushing their RSR-020 setup, the Yokomo RS-644R2 main shaft adds a solid central drive that resists twist under load. It is aimed at improving drive feel and keeping parts working together lap after lap.

Features and Benefits of RS-644R2

Compatibility: Engineered to match the Yokomo RSR-020 chassis specifications.
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.

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.
