Clutch Disc 5-87610049-0 Direct Replacement for Isuzu 4JH1 with High-strength Steel Hub and Torsional Damper

Clutch disc (friction plate) transmits engine torque from the flywheel to the transmission input shaft. Provides smooth engagement and dampens torsional vibration for Isuzu 4JH1 diesel engines.

• 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 4JH1 engines in various truck models.

• ISUZU NKR77 (light-duty truck)
• ISUZU NK, NM, NP series
