Precision Differential Upgrade for RS1.0 with Yokomo RS-503GH

The Yokomo RS-503GH 40T Differential Pulley and Case is crafted to sharpen the driveline response of the RS1.0 platform. It installs into both front and rear locations and matches the layout of RSR-010 and RSR-LFGT3RTR chassis for consistent operation across your vehicle.

Accurate Gear Engagement

The 40T design focuses on delivering consistent tooth contact to improve torque transfer and reduce drivetrain chatter. Precision machining promotes even wear across the gear teeth, which helps preserve component life under regular use.

Compatibility Across Chassis

This pulley and case fits the differential positions on compatible models, making it a reliable option whether you are replacing worn parts or upgrading to better meshing performance without altering core geometry.
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.

Is the RS-503GH suitable for track and practise sessions?

Yes. The RS-503GH is intended to improve gear engagement consistency, which benefits both competitive track use and regular practice runs by stabilising power delivery.

Should I check shim settings after fitting this unit?

Always check and fine tune shims and preload after installation. Correct spacing ensures optimal tooth contact and prevents premature wear or noisy operation.

What routine checks protect the differential?

Periodic cleaning, inspection for nicks or chipped teeth, and refreshing diff grease are simple steps that keep the pulley and case performing well over time.
