Performance Characteristics
1.High Smoothness: Large impacts are absorbed by the coil spring, and small high-frequency vibrations are absorbed by the hydraulic core, significantly improving comfort during long-distance driving.
2.High Reliability: Designed for heavy-duty commercial vehicles, it possesses strong fatigue resistance and wear resistance.
Usage and Installation Precautions
Pair Replacement: It is recommended to replace both the left and right rear suspension shock absorbers simultaneously to maintain cab balance and prevent uneven stress that could lead to oil leaks or tilting.
Installation Inspection: During installation, check the top and bottom rubber bushings of the shock absorber for damage. Damaged bushings will produce abnormal noises (metallic clanging sounds).
Oil Leak Monitoring: Regularly inspect the surface of the shock absorber. Obvious oil stains indicate seal failure, requiring immediate replacement to maintain damping effectiveness.
Torque Requirements: When tightening the mounting bolts, strictly adhere to the torque specified in the vehicle's maintenance manual to prevent loosening due to vibration.
