Shackle Bushing Suspension Bushing with Natural Rubber SBR Bonded to Steel for Direct OEM Replacement and Vibration Damping

Premium-quality direct replacement suspension component designed for Isuzu CXZ51K heavy-duty trucks equipped with the 6WF1 diesel engine. This shackle bushing isolates road vibrations, allows controlled leaf spring articulation, and prevents metal-to-metal wear.

• OE Quality: Manufactured to Isuzu dimensional and material specifications for perfect fit and reliable performance
• Rubber-Metal Bonded: High-strength adhesive bonding prevents separation under extreme loads
• Vibration Damping: Absorbs road shocks and vibrations, improving ride comfort
• Noise Reduction: Eliminates metal-to-metal contact, preventing clunks and squeaks
• Weather Resistant: Rubber compound resists aging, ozone, and temperature extremes
• Corrosion-Protected Sleeves: Steel sleeves coated to resist rust
• Restores Suspension Integrity: Eliminates play, restoring proper axle alignment and ride quality
• Direct Replacement: Matches OE dimensions - press-fit installation
• Cost-Effective: Affordable alternative to replacing the entire shackle assembly

This shackle bushing is specifically designed for Isuzu CXZ51K trucks with 6WF1 engine.

• ISUZU CXZ51K (heavy-duty truck, 6×4 or 8×4 configuration)
• May also fit other Isuzu heavy models with similar rear suspension (e.g., CYZ, EXZ) - verify compatibility

• 6-Cylinder, Inline Diesel, Turbocharged
• Displacement: 9.8L (9839cc)
• Application: CXZ51K, CYZ51K, EXZ51K series

Typical installation steps for shackle bushing replacement:

1. Safely lift and support the vehicle - support the axle or spring
2. Remove the shackle assembly or leaf spring (if necessary to access the bushing)
3. Place the shackle or spring eye on a press - support around the bushing outer diameter
4. Press out the old bushing - use a socket or drift that contacts the outer metal sleeve
5. Clean the bushing bore - remove rust, debris, and old rubber residue
6. Inspect the bore - check for ovality or damage
7. Lubricate the new bushing outer sleeve - apply thin film of soapy water or rubber-friendly lubricant
8. Press the new bushing into the bore - use drift that contacts outer sleeve only
9. Reinstall the shackle or leaf spring - torque mounting bolts to specification
10. Lower vehicle and test drive - listen for abnormal noise

• Material Verification: Rubber compound tested for hardness, tensile strength, and elongation per ASTM standards
• Dimensional Inspection: Inner diameter, outer diameter, length, and concentricity verified against OE blueprints
• Rubber-to-Metal Bond Test: Pull test ensures bonding strength exceeds specification
• Compression Set Test: Sample bushing compressed at elevated temperature to ensure permanent deformation within limits
• Aging Test: Accelerated heat aging (70°C for 70 hours) to confirm retained elasticity
• Visual Inspection: 100% checked for voids, cracks, flash, or missing rubber
• Packaged Safely: Bushing wrapped in plastic bag, boxed to prevent deformation

• Neutral export packing or customized packaging available
• Carton or wooden case for safe transportation
• Fast delivery for stock items
• Shipping by Express Air or Sea
