Core Features
- ASME-Certified Metal Gaskets: Spiral-wound stainless steel construction meets ASME B16.20 standards, withstanding 600℃ high temperatures and 15MPa pressure — 2× longer service life than composite gaskets in heavy-load operations.
- OEM-Matched Precision: All components tailored to DB58's 102×118mm bore-stroke and dry-type liner design, ensuring zero fitment issues and seamless installation with Doosan original engine parts.
- Complete Overhaul Solution: Includes every critical part for full DB58 engine rebuild — no separate purchases needed, reducing procurement time by 40% and maintenance costs by 35%.
- Heavy-Duty Durability: Forged pistons resist wear under 2200rpm continuous operation, while metal gaskets maintain sealing integrity against vibration and temperature fluctuations.
- Performance Restoration: Fixes compression loss (restores 28kg/cm² standard), oil/coolant leakage, and power drop, returning DB58 engines to factory-level torque and fuel efficiency.
- Rigorous Quality Testing: 100% pre-shipment inspection including gasket pressure sealing tests, piston dimensional verification, and bearing wear resistance checks.
