The XRAY 372913 X12 Aluminum Rear Bulkhead is built specifically for the X12 series 1-piece chassis and functions as the right-side support to stabilise the motor mount and rear assembly under race conditions.
Forged from high-grade aluminum, this rear bulkhead boosts chassis stiffness and helps limit motor movement that causes unwanted vibration. The added rigidity supports consistent weight balance and makes fine tuning easier on asphalt and high-grip surfaces.
Made to match the X12 one-piece chassis dimensions, this XRAY bulkhead installs with minimal fuss and is a solid swap for worn parts or setup improvements. It is a practical upgrade for club racers and experienced tuners alike.
