Rugged Drivetrain Support for the YZ-4S with Yokomo S4-503GHA

The Yokomo S4-503GHA gear differential case brings tougher construction to the YZ-4S chassis so your car copes better with hard runs. It helps stabilise power flow through corners and over rougher patches of track.

Why Choose This Gear Differential Case

  • Durability: Strong materials and precision manufacturing reduce the chance of failure under heavy use.
  • Compatibility: Matches YZ-4S family chassis and related variants for easy swap-in replacement.
  • Performance: Improves torque balance to help with predictable handling at speed.
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.

What chassis work with the S4-503GHA case?

Compatible chassis include B-YZ4SF, B-YZ4SF2-1, MOR-010 and MOR-020 as indicated by the component fitment list.

Will this upgrade survive off-road or rough surfaces?

The reinforced design improves resilience, but proper maintenance and checking for debris after rough runs will help extend life.

Can I use my existing internals when fitting this case?

In most cases internal gears and bearings transfer across, though inspecting parts for wear before reuse is recommended to ensure long term reliability.
