Rear bulk head for YR-X12 chassis

Machined aluminum rear bulk head engineered to fit the Yokomo YR-X12 1/12 competition chassis. The black anodized finish and beveled edge treatment reduce sharp corners and deliver a consistent surface finish. It functions 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 and is intended to replace the stock rear bulk head while preserving chassis geometry for consistent handling.

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 helps reduce surface wear and provides standard corrosion resistance expected from treated aluminum parts.

Tuning role: swapping to a machined aluminum rear bulk head can increase rear-end mounting consistency and alter stiffness characteristics relevant to 1/12 competition setups.
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.

What is the best way to install the Yokomo YX-20R on a YR-X12?

Begin by loosely fitting the bulk head to the rear chassis using the original fasteners. Check that suspension pick-up points and drivetrain align correctly, then progressively tighten screws while rechecking alignment to final torque.

Does the black anodized finish affect screw fit or clearance?

The anodized layer is thin and should not change mounting clearances in normal use. If a tight tolerance is suspected, deburr mating holes and use the original hardware to confirm fit before final assembly.

Should I check anything after the first test run?

Yes. After the first session inspect mounting screws for looseness and verify that suspension geometry has not shifted. Re-torque fasteners if needed and confirm no unexpected play at drivetrain attachment points.
