| Part Name: Rear Cab Shock Absorber with Spring |
| Part Number: 5001150-C1800 |
| Mounting Location: Rear support point of the cab (usually left/right, depending on the specific bracket) |
| Structure Type: Hydraulic damping + coil spring composite type |
| Main Materials: High-strength alloy steel (spring), wear-resistant rubber (bushing), hydraulic oil |
| Compression Damping: Determines the feedback force when the cab is pressed down. It is designed to be gentle to absorb sudden, severe impacts from the road surface. |
| Rebound Damping: Much greater than compression damping. Its core function is to prevent multiple consecutive aftershocks in the cab after a bump, ensuring the cab quickly returns to its balanced position. |

Performance Characteristics
Shock Absorption and Noise Reduction: Effectively absorbs vertical impacts between the cab and chassis, significantly reducing bumps and road noise during long-distance driving.
Stability Control: Limits excessive cab sway (nose-dive or roll) during cornering or braking, improving handling precision.
Durability: Optimized for Chinese road conditions, the springs have strong fatigue resistance.
Usage and Installation Precautions
Pair Replacement: To maintain cab levelness and damping consistency, it is recommended to replace both sides simultaneously.
Bushing Inspection: Before installation, check the top bushing for damage; cracks will cause abnormal noise.
Torque Specification: Tighten the fixing bolts to the standard torque to prevent loosening that could lead to uneven stress and breakage of the shock absorber.
Oil Leakage Prevention: During maintenance, observe the cylinder for hydraulic oil leaks; leaks will cause a rapid loss of damping force.
