Yokomo S4-002BRRA Aluminum Rear Bulk Head (Right) for YZ-4S, machined aluminum right rear bulkhead for 1/10 touring chassis  [S4-002BRRA]

Aluminum rear bulk head (right)

A right-side aluminum rear bulk head engineered for Yokomo YZ-4S series chassis, the S4-002BRRA provides a rigid mounting point for the rear suspension assembly on 1/10 electric touring setups. The component focuses on predictable geometry and consistent fit to support setup adjustments and track durability.

In practical use the part occupies the right rear bulkhead location on compatible YZ-4S platforms, offering a stiffer metal alternative where precise suspension alignment and repeatable handling are required. Its machined surface and anodized finish resist wear from normal assembly and routine maintenance.

Installation is straightforward for chassis prepared to accept this part: align the bulk head with the chassis mounting points, secure with the existing hardware, and verify clearance for nearby components such as the motor, ESC, and rear suspension links. During setup, treat the aluminum bulk head as a tuning lever—changes to mounting stiffness and geometry at this point affect rear grip and transient response.

Choose this bulk head when you need a durable, dimensionally consistent mounting point for rear-end setup work on YZ-4S platforms, keeping in mind matching left/right components and regular inspection of fasteners after track use.
