High-Quality Wear-Resistant Rubber/Metal Composite Shackle Bushing for ISUZU Trucks Reduces Friction and Vibration Direct OEM Replacement

The Shackle Bushing (OEM Numbers: 9-51151032-0 / 9511510320) is a premium-quality, direct replacement suspension component designed specifically for ISUZU trucks and compatible commercial vehicles. This precision-engineered bushing is a critical component of the vehicle's leaf spring suspension system, installed in the spring shackle bracket to connect the leaf spring to the chassis frame.

By providing a durable, low-friction pivot point, this bushing allows the leaf spring to flex and articulate smoothly while absorbing road shocks and vibration, ensuring stable vehicle handling and ride comfort.

• OE Quality: Manufactured to strict ISUZU dimensional and material specifications for perfect fit and function
• Durable Construction: High-quality materials resist wear, deformation, and cracking for long service life
• Vibration Absorption: Provides smooth suspension articulation and reduces road shock transmission
• Low Friction Design: Reduces wear on spring and chassis mounting points
• Restores Ride Quality: Eliminates suspension noise and poor ride comfort caused by worn bushings
• Protects Suspension Components: Prevents premature wear of leaf springs and mounting hardware
• Direct Replacement: Simple installation during suspension service
• Cost-Effective Maintenance: Essential component for suspension system reliability
• Long Service Life: Engineered to withstand the rigors of heavy-duty commercial operation

Professional installation recommended. Proper suspension service is essential:

1. Raise and secure the vehicle – Safely lift the vehicle and support on jack stands
2. Support the axle – Use a jack to support the axle and relieve spring tension
3. Remove the shackle bolts – Remove the bolts securing the shackle to the spring and chassis bracket
4. Remove the old bushing – Press or push out the old bushing from the shackle or spring eye
5. Inspect the shackle bracket – Check for wear, damage, or elongation; replace if necessary
6. Inspect the spring eye – Check the spring eye for wear or damage
7. Clean thoroughly – Clean the mounting surfaces and bushing bores
8. Prepare the new bushing – Inspect the new bushing and apply appropriate lubricant if specified
9. Install the new bushing – Press the new bushing into the shackle or spring eye
10. Reinstall the shackle – Reconnect the shackle to the spring and chassis bracket
11. Tighten bolts – Tighten shackle bolts to manufacturer specification
12. Lower the vehicle – Lower the vehicle to the ground
13. Check suspension operation – Bounce the vehicle to verify smooth suspension articulation
14. Road test – Test drive to verify ride quality and suspension function
