Searching for a warp-resistant Mitsubishi 4G63 or 4G64 cylinder head? This premium SOHC 8-valve assembly (OEM: MD188956) is manufactured from gravity-cast aluminum alloy to eliminate deck distortion in high-hour industrial engines. It provides exact fitment for Mitsubishi FG25 forklifts and L200 pickups. Available for global wholesale dispatch.
The Mitsubishi 4G63 and 4G64 “Sirius” engines are iconic powerplants, renowned for their versatility across automotive and industrial sectors. In their SOHC 8-valve configuration, these engines act as the primary workhorse for material handling fleets and light commercial vans worldwide. While Mitsubishi’s innovative engineering ensures a reliable powertrain, these engines face a specific maintenance pain point: deck warping. Because the head is manufactured from an aluminum alloy to save weight and improve heat dissipation, any cooling system failure or localized overheating quickly leads to surface distortion, blown head gaskets, and cylinder head cracking.
Ruich Value provides a high-durability aftermarket solution for these high-stress environments. Our MD188956 cylinder heads are gravity-cast using high-grade aluminum alloy, which offers superior thermal stability and density compared to low-cost alternatives. We have precision-machined the valve seats and guides to micron-level tolerances, ensuring optimal oil control and compression seal. With a factory-spec deck flatness tolerance of ≤ 0.05 mm and rigorous 3MPa pressure testing, our heads ensure your TCM forklifts or Delica vans return to the job site with zero compromises in reliability.

Forklifts operate in dusty environments with limited airflow, often leading to cooling system buildup. Because aluminum expands more than cast iron, any overheating event causes the cylinder head deck to warp away from the block. Our heads utilize reinforced gravity casting to minimize this thermal movement, but keeping the radiator clear is vital.
No. This MD188956 is specifically for the SOHC 8-valve (single camshaft) engines. The 16-valve 4G63T (turbo) used in performance cars like the Lancer Evolution uses a DOHC configuration with different oiling ports and combustion chamber geometries. They are not interchangeable.
For the Mitsubishi 4G63/4G64, head bolts should be torqued in the factory sequence to 105 Nm (77 ft-lb). Since these are aluminum heads, ensure the block threads are perfectly clean and dry before installation to prevent hydraulic cracking of the block casting.
This specific SKU is for a bare cylinder head casting. This allows you to transfer your existing 8-valve SOHC components if they meet service limits. We also offer complete head assemblies (including valves, springs, and camshaft) for rapid fleet replacement. Please contact us for wholesale pricing on complete units.
