Toyota 1HD-T Cylinder Head 11101-17042 (4.2L Turbo 12V)

Legendary Performance: Toyota 1HD-T Cylinder Head

The Toyota 1HD-T 4.2L Turbo Diesel engine is the holy grail for many Land Cruiser enthusiasts, powering the iconic HDJ80 series. Unlike the indirect-injection 1HZ, the 1HD-T utilizes a direct-injection system to deliver superior torque and fuel efficiency. However, high mileage and elevated exhaust gas temperatures (EGTs) from performance tuning can lead to cracking around the injector nozzles and glow plug ports. A compromised head risks severe engine damage in these high-value vehicles.

Ruich Value manufactures a premium aftermarket replacement for the 11101-17042 cylinder head. Engineered specifically for the **12-Valve SOHC** configuration, our casting features reinforced alloy material in critical thermal zones to prevent the cracking issues inherent in the original design. Precision machined for direct injectors, this head restores the factory performance of your Land Cruiser 80, ensuring it remains the ultimate overland machine.
