[Knowledge Classroom] The garage master teaches you what key points you need to know when choosing shock absorbers!
1. Compatibility and specifications
-
Original equipment specifications (OEM) comparison:
Confirm whether the shock absorber model, size, fixing hole spacing and interface are completely matched with the original vehicle. -
Vehicle-specific design:
Choose shock absorbers designed specifically for this model and avoid forced modifications that may affect the structure or safety. -
Load and suspension travel:
Select appropriate load and travel settings according to vehicle weight and purpose (private, truck, off-road).
2. Shock-absorbing structure and type selection
-
Single-tube/double-tube shock absorbers:
The single-tube structure has a fast response, good heat resistance and easy maintenance; the double-tube shock absorber has a softer shock absorption and lower cost. -
Hydraulic / Pneumatic / Electronic shock absorber:
Hydraulic shock absorbers are durable and stable, and relatively easy to maintain; pneumatic shock absorbers are highly comfortable, but have a complex structure and high maintenance costs; electronic shock absorbers require special computer diagnostic equipment.
3. Maintenance convenience
-
Easy to disassemble and install:
Is the shock absorber design easy to disassemble and replace parts? Do special tools are required? -
Can parts be replaced individually?
Such as shock absorbers, slingshots, tower top seats, rubber rings, etc., can they be replaced separately? -
Support repair parts supply:
Choose a brand that has a good supply of parts to facilitate future maintenance and repairs.
4. Durability and quality
-
Sealing design:
The quality of shock absorber oil seal can prevent oil leakage and water ingress. -
High temperature/corrosion resistant materials:
Use high-quality steel, paint and rust-proof treatment. -
Brand reputation and warranty period:
Choose a reputable brand and pay attention to the original warranty period.
5. Performance and comfort
-
Suspension damping adjustability:
Some shock absorbers can be adjusted in hardness (damping), which is convenient for tuning according to road surface or load. -
Ride balance/roll control:
Test the actual effect of shock absorbers on reducing sway and stabilizing the chassis. -
Noise performance:
The abnormal noise produced by the shock absorber during operation is related to the installation and structural design.
6. Maintenance technical cooperation
-
Maintenance information and support:
Does the shock absorber brand have detailed maintenance manuals, installation instructions and technical support? -
Whether professional tuning or computer settings are required:
Some advanced or electronic shock absorbers require special instruments to set up, and it is necessary to evaluate whether the maintenance equipment is compatible. -
Test tool requirements:
Whether a shock absorber damping test bench or other special tools are needed to assist in maintenance.
7. Price and cost performance
-
Replacement and repair costs:
Evaluate the initial purchase cost of the shock absorber and the subsequent cost of repair and replacement parts. -
Maintenance cycle and service life:
The life of the shock absorber and whether it is easy to maintain and repair in the future.
8. Post-installation inspection
- Check the shock absorber for oil leakage, abnormal noise, and tightness of fixing screws.
- Ensure that the shock absorber rebounds smoothly without getting stuck.
- Check the coordination with other parts of the suspension system (such as springs and connecting rods).
Summarize
When choosing car shock absorbers, maintenance technicians should consider "easy installation and disassembly, high durability, sufficient parts supply, and good brand technical support" as the major premise, while taking into account performance, structure and compatibility with the original car to ensure that installation and future maintenance can be done with ease.
