Universal RB20 / RB25 / RB26 head drain kit

NO DRILLING, NO TAPPING, NO HASSLE

Our direct-fit head drain kit is designed to improve oil control in high-performance Nissan RB engines, it helps minimise oil accumulation in the cylinder head during hard driving, whether you’re hitting the drag strip, drift track or street.

This kit provides a dedicated return path for oil to flow from the cylinder head back to the sump. By reducing oil pooling in the head, the system helps prevent excessive oil from being pushed through the valve cover breathers and into the catch can.

Our -10AN o-ring seal billet port drain features a robust 2-point rotational mounting bracket for secure, reliable fitment. The adjustable design allows the fitting to be rotated and positioned to achieve the ideal outlet direction while accommodating surrounding clearances.

Finished in black anodised 6061 aluminium, the fitting is built for durability while maintaining a clean, professional appearance.
