Clutch Disc for Isuzu 4HK1 NP4H Truck with OEM Standard Fitment and Torsional Damper

Function: Clutch disc (friction plate) transmits engine torque from the flywheel to the transmission input shaft. Provides smooth engagement and dampens torsional vibration for Isuzu 4HK1 diesel engines.

The Clutch Disc (OEM Numbers: 5-87610080-0 / 5876100801, and 8-97362235-1 / 8973622351) is a premium-quality, direct replacement drivetrain component designed for Isuzu 4HK1 diesel engines, commonly used in Isuzu NP4H series trucks (likely NPR, NQR variants).

• OE Quality: Manufactured to Isuzu dimensional and performance specifications for perfect fit and reliable torque transmission
• Torsional Damper: Multi-spring design absorbs vibrations, reducing gear noise and driveline shock
• Premium Friction Material: High-copper or organic linings provide excellent heat dissipation and long wear life
• Precision Splined Hub: Heat-treated for durability, ensures smooth sliding on input shaft
• Riveted Construction: Securely bonded linings prevent delamination
• Restores Clutch Performance: Eliminates slipping, judder, and hard shifting
• Direct Replacement: Matches OE diameter and spline - simple installation
• Cost-Effective: Affordable alternative to genuine OEM discs

This clutch disc is specifically designed for Isuzu 4HK1 engines in NP4H trucks.

• ISUZU NP4H (likely N-series medium trucks - NPR, NQR with 4HK1)
• May also fit other Isuzu models with 4HK1 engine (e.g., NPR75, NQR75, FRR) - verify

• 4-Cylinder, Inline Diesel, DOHC, Common Rail
• Displacement: 5.2L (5193cc)
