DJ Rock HG50 Engine Cylinder Head Gasket

Engine Cylinder Head Gasket for Suzuki and Geo

DJ Rock HG50 is a premium engine cylinder head gasket built to seal the joint between the engine block and cylinder head. It helps maintain compression while controlling coolant, oil, and combustion gas leakage in supported Geo Metro and Suzuki applications.

Key Features

• Premium-grade cylinder head gasket for engine sealing service
• 74 mm cylinder bore diameter
• Built to meet or exceed OEM quality expectations
• MLS construction for modern engine sealing performance
• Designed for use on select Geo Metro, Suzuki Swift, Samurai, and Sidekick engines

Detailed Description

DJ Rock HG50 is an engine cylinder head gasket for 1986-1997 Geo and Suzuki applications, including 1995-1997 Geo Metro, 1989-1997 Suzuki Swift, 1990-1995 Suzuki Samurai, 1989-1994 Suzuki Swift, 1986-1989 Suzuki Samurai, and 1989 Suzuki Sidekick. This gasket is engineered for reliable sealing under high heat and pressure, with multi-layer stainless steel construction used in modern engine applications to improve micro-sealing across the head and block surfaces. The 74 mm bore diameter supports the listed engine configuration, and the premium grade type reflects its OE-style service focus. This part number, HG50, is a direct-fit sealing component for repair work where compression loss or fluid leakage has occurred. This part cross-references MAHLE 5759 for the same application.

Common Problems It Can Address

• Coolant leakage at the cylinder head sealing surface
• Oil seepage between the head and engine block
• Combustion gas loss that reduces compression
• Overheating caused by a compromised head gasket seal
• Rough running or misfire conditions related to sealing failure

Installation Notes and Tips

Inspect the cylinder head and block for warpage, corrosion, or surface damage before installation. Clean all mating surfaces thoroughly and follow the manufacturer’s torque sequence and torque specifications during assembly. Replace torque-to-yield head bolts rather than reusing them, since clamping force can be reduced after removal. Confirm engine code and bore size before ordering HG50.

Quality Assurance

DJ Rock HG50 is manufactured to meet or exceed OEM quality standards for cylinder head gasket service. Its sealing materials and construction are selected for durability, temperature resistance, and consistent compression sealing in the listed Geo and Suzuki applications.
