Detailed Description

DJ Rock HGS944 is engineered for complete cylinder head service on 1992-1997 Lexus SC300, 1993-1997 Lexus GS300, and 1993-1997 Toyota Supra models. This engine cylinder head gasket set supports proper sealing between the cylinder head and engine block, which is critical for compression retention and fluid separation. The set is built around an 86 mm bore diameter and uses non-asbestos materials selected for modern engine sealing demands. This part cross-references MAHLE HS54034 for the same application.

For buyers searching for a Lexus GS300 head gasket set, Toyota Supra cylinder head gasket set, or Lexus SC300 top-end gasket kit, HGS944 provides the sealing components needed for cylinder head replacement and related upper-engine service. Part number HGS944 is also listed with interchange references including HS26297PT-1 and HS34485.

Common Problems This Part Helps Address

• Coolant leakage at the cylinder head sealing surface
• Oil seepage from upper-engine gasket interfaces
• Combustion pressure loss from a failed head gasket
• Intake, exhaust, and valve cover sealing issues during head service
• Leak paths created during cylinder head replacement or rebuild work

Installation Notes and Tips

Clean all mating surfaces thoroughly before installation and inspect the cylinder head and engine block for warpage or damage. Follow the factory torque sequence and torque specifications for the vehicle, and replace torque-to-yield head bolts rather than reusing them. Verify all sealing surfaces, passages, and alignment points before final assembly. HGS944 is intended for professional engine service where precise sealing is required.

Quality Assurance

DJ Rock HGS944 is manufactured with non-asbestos materials and built to meet or exceed OEM quality standards. The set uses sealing materials selected for heat, oil, and coolant resistance in upper-engine applications.
