Aluminum right rear bulk head — tuning and fit

The S4-002BRRA is a right-side aluminum rear bulk head made for the Yokomo YZ-4S chassis, offering a rigid attachment point for the rear suspension assembly on 1/10 electric touring models. Its design emphasises repeatable geometry to help with setup changes and consistent track performance.

When installed at the right rear position on compatible YZ-4S platforms, this machined and anodized part replaces more flexible stock components to give crisper suspension responses. The finish protects the material from routine wear and keeps the mating surfaces true.

Installation is normally direct: line up the bulk head with the chassis bosses, fasten using the stock hardware, and check clearances around the motor, ESC, and rear links. Use the bulk head as a tuning lever: altering mounting stiffness here changes rear grip and transient reactions.

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 this change my setup balance significantly?

Moving to an aluminum bulk head typically stiffens the rear mounting, which can make geometry adjustments more predictable and slightly alter balance toward reduced flex.

Is the part ready to bolt on out of the box?

Yes, the S4-002BRRA is designed to use existing chassis mounting points and standard fasteners for a straightforward swap.

Does the finish affect weight or clearance?

The anodized machined surface adds negligible weight while protecting against abrasion; always confirm there is adequate clearance for the motor and suspension travel after fitting.

What routine checks should I include post-install?

After installation, check screw torque after a few runs, inspect for any rubbing on adjacent parts, and re-evaluate rear ride and handling to fine-tune settings.
