More consistent handling with the Yokomo MS-503GHA aluminium case

The Yokomo MS-503GHA Aluminum Gear Differential Case replaces conventional resin housings to offer superior thermal management and steadier operation. This helps avoid handling shifts caused by oil viscosity changes during prolonged or hot running.

Improved alignment and cleaner power transfer

Manufactured from robust aluminium, the case enhances fitment and drivetrain accuracy for smoother torque delivery. The pulley stays resin to keep original engagement geometry while the aluminium shell upgrades durability and control.

Specifications

  • Material: Aluminum Case, Resin Pulley
  • Tooth Count: 38T
  • Compatibility: MSR-010, MSR-010A

A practical upgrade for enthusiasts and racers looking to reduce temperature related handling drift and gain more predictable performance.
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 case work with standard diff oils?

Yes, it is compatible with standard diff oils; the aluminium shell simply helps the oil stay within a more stable temperature range during extended running.

Does the upgrade affect tuning options?

Tuning remains the same, but you may find oil choices behave more predictably due to improved heat dissipation, which can make setup changes easier to evaluate.

How straightforward is fitting to MSR chassis?

Fitting aligns with the original differential installation for MSR-010 and MSR-010A models; basic workshop tools and careful alignment are all that is needed.
