Yokomo YX-20R Rear Bulk Head (R) for YR-X12  [YX-20R]

This is an aluminum rear bulk head engineered for the Yokomo YR-X12 1/12 competition chassis. The part uses black anodized aluminum with beveled edge treatment to reduce sharp corners and provide a consistent surface finish. It serves as the rear mounting structure that locates suspension and drivetrain attachment points on the rear section of the chassis.

Compatibility is stated for YR-X12 and YR-X1219 chassis platforms. The component retains the original mounting footprints, intended to replace the stock rear bulk head while preserving chassis geometry for handling consistency.

Installation notes: align the bulk head with the chassis rear section and secure using the existing mounting positions and hardware from the vehicle; confirm alignment before final torque to ensure correct rear suspension and drivetrain positioning. The anodized finish reduces surface wear and offers standard corrosion resistance expected from treated aluminum parts.

Tuning role: swapping to a machined aluminum rear bulk head can change the stiffness and mounting consistency of the rear assembly, making it a straightforward option when adjusting rear-end feel for 1/12 circuit setups.
