Better temperature control from the Yokomo MS-503GHA case

The Yokomo MS-503GHA Aluminum Gear Differential Case is made to replace fragile resin housings and offers improved thermal transfer and steadier behaviour. This part helps prevent oil from thinning out too quickly on long or hot track days, so handling stays consistent.

Accurate fit for cleaner power delivery

Crafted from durable aluminium, the case tightens tolerances in the gearbox and promotes smoother drive response. The pulley remains resin to preserve original gear engagement and compatibility with existing setups.

Specifications

  • Material: Aluminum Case, Resin Pulley

It improves heat transfer compared with resin, which helps the diff oil stay cooler and keeps the car balanced over extended sessions.

Which models is it compatible with?

Does it change differential feel?

You may notice firmer and more consistent steering as the aluminium keeps oil viscosity steadier under load compared with a resin case.
