• ISUZU NKR69N – 2006 model (Japanese domestic market with 4JG2)
• ISUZU NPR / NQR series – selected chassis with 4JG2 engine
• ISUZU Trooper / Bighorn (UB2) – 1991–2000, 3.1L 4JG2 / 4JG2T
• ISUZU MU (UC) – 1991–1998, 3.1L diesel
• ISUZU Faster / TF series – 1993–1998 pickup
• ISUZU Wizard – 1992–1998
• Opel Monterey A (M92) – 1992–1999, 3.1TD
• Honda Horizon – 1994–1998

• Industrial applications – welding generators, water pumps, marine auxiliary units

The part is also cross-compatible with 4JG1 engines (smaller 2.8L variant) using the same head gasket design.

• One Gasket Covers Multiple Vehicle Platforms – Services NKR69 delivery trucks, Trooper SUVs, Opel Monterey off-road vehicles, and TCM forklifts
• Prevents Common 4JG2 Failure Modes – Restores sealing interface, preventing coolant from entering combustion chambers
• Reduces Workshop Diagnostic Time – Multiple cross-reference numbers eliminate time wasted searching through conflicting parts catalogs
• ISO 9001 Certified with Batch Traceability – Each production batch manufactured in ISO 9001:2015 certified facility
• Light Weight and Compact Packaging for Export – Approximately 0.5 kg with economical shipping dimensions

Each production batch undergoes comprehensive verification:

• Fire ring bore alignment – Laser measurement against 95.4 mm ±0.03 mm tolerance
• Coolant and oil port positioning – Optical comparator inspection within ±0.2 mm of OE blueprint
• Gasket thickness – Digital micrometer measurement; compressed thickness 1.2 mm ±0.05 mm
• Material composition – Spectrographic analysis per batch
• Elastomer coating integrity – Visual and adhesion test
• Elastomer compression set – ISO 815 standard compliance
• Fire ring crush test – Hydraulic press applies 20,000 N force
• Dimensional check – Full CMM inspection against original engineering drawings

The manufacturing facility holds ISO 9001:2015 certification with batch traceability available for wholesale orders.
