Improve SD2.0 handling with the Yokomo Y2-302ARB component

The Yokomo Y2-302ARB aluminium rear bulkhead offers a straightforward way to change the behaviour of an SD2.0 chassis. Hobbyists can pick a 3-gear setup to emphasise turn-in, or fit a 4-gear arrangement when more rear traction is needed for heavier throttle corners.

How gear choices affect handling

Adjusting the counter gear and motor mount positions lets you swap between drivetrain types. The 3-gear layout delivers quicker steering feedback while the 4-gear layout redistributes torque for improved rear-end bite during acceleration.

Compatibility and installation notes

This aluminium bulkhead is compatible with SDR-020, SDR-020P, and SDR-020R chassis and is designed for a clean installation. Its solid build helps preserve gear alignment and contributes to a stiffer rear end for repeatable lap times.
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 upgrading to aluminium change handling a lot?

Aluminium improves mounting stability and reduces flex compared to softer materials, which can produce more predictable handling especially under load.

Do I need to change gear ratios when switching layouts?

Not necessarily, but you should check motor load and gearing to ensure the motor runs efficiently after changing from 3- to 4-gear setups.

Any tips for first time installers?

Take care to set correct backlash, tighten mounting screws evenly, and inspect gear mesh after a few short runs to confirm everything is secure.
