Toyota Land Cruiser HJ61 12H-T Turbo Oiling & Cooling Solutions

PROTECT THE HEAD.

The 12H-T is a million-mile engine, but its 30-year-old factory plumbing is its greatest liability. Heavy diesel vibrations snap rigid OEM oil pipes, while internal corrosion creates "pinhole leaks" that lead to catastrophic head failure.

GryphonTek provides the professional foundation for every 12H-T build. Whether you are performing routine maintenance on original lines or executing a high-performance turbo upgrade, we provide the exact, vibration-resilient fittings you need.

Why 12H-T Owners Trust GryphonTek Engineering?

Cylinder Head Security

Our exclusive -6AN high-flow water kits eliminate factory pinhole leaks. The rust-proof stainless braid ensures your cooling system never bleeds out during long-distance touring.

Diesel Fatigue Defense

Unlike rigid pipes that act as levers on their own welds, our PTFE braided lines soak up 4.0L straight-six harmonics, preventing vibration-induced cracks for life.

CT26 Specialized Fit

Engineered specifically for the Toyota CT26 combo flange, providing the -4AN feed path and high-volume 3/4" return path needed for bearing stability.
