Key Features
- Genuine OEM Combustion Integrity — Manufactured to exact Multiquip specifications, ensuring proper compression sealing, combustion chamber geometry, and port alignment critical to engine performance.
- Direct Bolt-On Replacement — Matches the original head gasket surface, valve seat positions, and fastener pattern for a straightforward swap on compatible engines.
- Broad Fitment Coverage — Confirmed for G-4.5R, GA4.5R, GA4.5RA portable generator models and QP3TE, QP-40TE MQ trash pump models from a single part number.
- Sustained Engine Output — A correctly seated cylinder head maintains proper compression ratios, directly supporting steady power delivery in both generator and pump applications.
- Fuel System Safety Compliance — Proper cylinder head sealing prevents combustion gas leakage around the head gasket interface, reducing the risk of heat damage, oil contamination, and unsafe operating conditions.
The cylinder head complete forms the top of the engine's combustion chamber, sealing the cylinder bore and housing the intake and exhaust valves. It works in conjunction with the head gasket to contain combustion pressure and direct airflow through the engine, which directly determines how much power the engine can produce. When a cylinder head is cracked, warped, or improperly sealed, compression drops, the engine runs poorly or overheats, and in severe cases combustion gases can contaminate the oil supply — making timely replacement essential to keeping the engine operational.
