Tune Your RS1.0 with the Yokomo RS-503GH 40T Differential

The Yokomo RS-503GH 40T Differential Pulley and Case is built to refine the drivetrain behaviour of your RS1.0 setup. Suitable for installation in both front and rear positions, it integrates cleanly with RSR-010 and RSR-LFGT3RTR chassis to improve gear engagement accuracy and on-track consistency.

Precision 40T Tooth Mesh

The 40-tooth configuration ensures accurate tooth contact for steadier torque transfer and reduced drivetrain lash. Careful machining helps the gear teeth seat evenly, lowering wear and supporting longer service intervals for your differential parts.

Front and Rear Fitment

This RS-503GH unit is compatible with the front and rear differential housings on supported chassis, making it a straightforward replacement or upgrade for enthusiasts looking to balance handling and reliability without complex modifications.
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-503GH fit both front and rear differentials?

Yes. The RS-503GH is designed for use in the front and rear positions of RS1.0 compatible chassis including the RSR-010 and RSR-LFGT3RTR, allowing uniform gear ratios across the drivetrain.

Do I need special tools to install this pulley and case?

Basic hobby tools are usually sufficient: hex drivers, a small screwdriver and diff grease. A torque driver and feeler gauges help ensure correct preload and shim settings for best gear engagement.

How should I maintain the differential for long life?

Regular inspection, cleaning of gear teeth and fresh diff grease will extend service life. Check for play and wear after several sessions and replace components at the first sign of uneven tooth wear.
